In some circumstances, the window for a project is in a "hyper thin mode". I think it might have to do with switching between single screen & external monitor mode -- the window gets compressed somehow, and locked into this size ratio.
The window is about 3 pixels wide, and there's no way to expand it, grab it, or otherwise access it. Seriously, the window is a sliver with a shadow.
"Reset window placement" doesn't help. It just moves the hyper thin window to another place on the screen.
Also not effective for getting it expanded to a usable width:
If the menu item Window > Zoom
were enabled, that might work. But it's not enabled.
This has made TimeNet pretty much unusable for me, because I can't get to the project to add items.
I can email you screen grab if necessary.
