Try 2.3.5 (it's a beta release). It's still collapsing in that release, but MUCH less often. So they are making progress.

In 2.3.1.0 the tree collapses constantly.

They claim this is resolved. How do we get them to fix this? 

I've been running Tower with no issues - ran the trial for 30 days and have the full paid version now.

I am on Windows 7 here at work.

This seems very unlikely, but is it possible this is related to Git on Windows in general? I installed a trial of Tower for Git and am noticing that repos are closing in a similar way when I leave the app in the background for a while. Doubtful, but it's an odd bit of synchronicity.

This issue is not resolved!

Started using Tower - had to pay $99 for it, but worth the money due to lack of response from Source Tree team.

Good luck everyone....

I just tried this in version 2.3.1.0 and the problem is STILL there.

@Mike Corsaro bump

DEAR ATLASSIAN. WHEN WILL THIS ISSUE BE FIXED????

Not resolved in 2.2.4.0 beta

I agree, definitely not resolved in version 2.1.11.0 (Windows).

Not updated in V 2.1.11.0 for windows either

Yip, @Johnny Mikkelsen puts it well.

Definitely not resolved; please reopen.

I too am still seeing this issue on version 2.1.10.0 for Windows.

It's like a daily digital tug of war. I unfold stuff, then SourceTree collapses it. Then I unfold things again, and then SourceTree collapses it. I don't know why this is marked as resolved, it very much seems like a persistent issue. Please re-open this issue so I can vote for it.

One more confirmation for you in ver 2.1.10.0.  I am unable to consistently repro, though.  I do agree with Zachary above that it seems to happen when re-gaining focus.  And it is only the active tab that is having the issue.

Confirmed. The issue is still happening in 2.1.10.0.

I concur, Version 2.1.10.0 this is still occurring. I can easily reproduce the collapse most times when I un-focus SourceTree, then re-focus SourceTree.

Open SourceTree > Open Remotes and "origin" on the left > click a different application window > click SourceTree again

What I observe is that there's a small progress bar at the top of the left area box where Remotes/Stashes/etc live which shows up for a quick moment then disappears again. Most times when that progress bar shows up my tree-view collapses.

Version 2.1.10.0, not fixed.

Please fix this, it is a real pain!!

Dear Atlassian, when will this fix become generally available?

I too have switched software - Sourcetree has become too unresponsive and keeps crashing.  Would be nice to go back to the previous version before Atlassian decided to add unnecessary bells and whistles to the UI which basically renders the software unusable.  Even the minimize, maximize, close icons in the top right don't work properly.

This disruptive issue has been hanging around for much too long. Time to give GitKraken a try. It's also free and multi-platform. 

Yes, I am confused, as well, because I just checked again and the issue occurs in v2.2.0.

It does not happen on every refresh. From my point of view, it happens randomly and perhaps that makes it difficult to track down. I cannot seem to find a specific scenario that causes the collapsing. It may happen right after I switch to SourceTree after having made some changes, so it refreshes after new uncommitted changes. Or with no changes at all, I just switch to the application after having minimized it to the taskbar. I really wish I could find a specific scenario in order to assist more in fixing this issue.

Fix Version/s: 2.1.6-beta-0
Status: RESOLVED

Also, I would like to note that this issue keeps happening in the most recent beta (v2.1.8.0)

I just installed v2.2.0-beta and the problem still exists.

I'm confused. Is this fixed, or not?

I just installed v2.2.0-beta and the problem still exists.

I completely agree.

Also, I would like to note that this issue keeps happening in the most recent beta (v2.1.8.0), as well.

This issue is extremely annoying. I even uninstalled Sourcetree after a month of struggling with this. The whole app is unusable for me now.

Yes, this bug is really annoying. When will there be a stable version where this is fixed?

That is excellent news, Michael!

Thank you very much for the update.

We have a fix going out to beta this week.

Can't use Source Tree with this happening - expand my remote branches and within 1 second it collapses.

using version 2.1.2.5

I agree, up the priority, very, very annoying, currently using 2.1.2.5 RTM

I can verify that this happens in version 2.1.4.0-beta, as well.

This Bug became really annoying with one of the last updates.
Sometimes the branch tree even collapses while I'm expanding it because something refreshes. Most of the time the tree view won't stay expanded longer than a few seconds, because there is almost every time some action causing a refresh.

Please fix this ASAP!

I'd suggest this should have a higher priority. It makes ST unusable for me.
