The <windows> section turns from <windows>[informationy stuff]</windows> into <windows />. I am using a text editor, so that's how I know this. Anyways, this behavior is annoying, because it makes the file not load properly! As a result I don't see anything open up. I either have to manually edit the persist file (which oh so "persistently" keeps doing this every time I close the thing trying to copy and paste some script) and reinclude the necessary tags, or go to the project sections and choose a Layout from there. Yeah, I know it's an unstable build and all, but this is really just stupid.
