I noticed when I start the new x64 version of TG2 (2.3 build 2.3.20.1) that it always starts with a window size of around 1000 x 730. I've tried maximizing to my 1680 x 1050 monitor and quitting, but it always starts up at the same 1000 x 730 size. I also tried manual resizing to full screen by dragging the sizing controls, but again, it doesn't retain the size/position when restarted.
I don't remember the previous version doing this -- maybe I'm overlooking something, though I didn't see anything in the preferences.
Okay, I answered my own question. All I need to do is go to the properties and select "Run | maximized". I'm thinking I'd rather have the program "remember" the size/position when I exit, but since I run it maximized most of the time, its no big deal.
Also, is there a problem running both the x32 and x64 versions on the same computer (without negative interaction between the two versions?)
