Opening and closing Sourcetree causes Pageant to crash/close

I have installed putty and pageant outside of Sourcetree, and I have Pageant startup during OS boot so my key-file is always ready.

Didn't quite notice it at first, so not sure which version it started at, but Sourcetree now causes Pageant to crash/close when it opens or closes, causing e.g. git commands and such from command line to suddenly start to failing for no apparent reason.

Whenever I open or close Sourcetree now, I have to reopen Pageant and reload my key, including entering a long passkey. Super annoying. Sourcetree shouldn't close or cause any other applications to crash when it opens or when it closes.

It happens on all 3 computers of mine. All running latest Windows, latest Pageant, and latest Sourcetree.
