Unable to edit a page- window extermenly small (chrome) or non-existent (i.e)

Starting friday afternoon when I go to edit a page in confluence in Chrome (my primary browser) the edit window is extremely smal (unusable), and there is a large amount of white space underneath the preview/save/close buttons (see screen shot).

In IE the whole page is white- I don't even get an edit box. What happened? I tried shutting down the app and reopening, rebooting my computer etc.. I tried looking on your knowledge base for troubleshooting tips and didn't see anything

Please help! I can;t do my work.. Thanks!
