I've been trying this version out and whenever I open a new tab from the explore project thing, it opens one in the bottom left hand corner instead of the biggest window, and it's making working with this version a nightmare, especially because it never used to work like this in 3.2.1. I can't work on my game if I have to keep dragging the new tabs out instead of them just being there like they used to be forever. Am I doing something wrong here?
I tried to find a way to reproduce this. Apparently, some of the panels in AGS has an invisible "marker" on it that tells it to open new tabs there all the time. And similar situation may happen if you keep dragging panels around and resizing them until that "main panel" appears in the corner.
Well, I see two options here:
1) Keep rearranging panels in "inverse" way, like in the "slide pieces puzzle", to push that pane out to the place you want. In other words, if you want it to go up and right, then drag & place something to the left and bottom.
2) Go to "%USERPROFILE%/AppData/Local/AGS" and delete Layout.xml. That should reset the layout to defaults, after which you may adjust it to your preference again.
