Hi artfizz:
I had the same problem with Firefox a while back, and found a fix doing the following:
1. Close Firefox
2. Start -> Run -> %appdata%
3. Open Mozilla folder -> Firefox -> Profiles -> enpmvfpd.default (not sure if this would be named the same) -> delete/rename 'content-prefs.sqlite'.
4. Restart Firefox, and default window settings are restored.
I don't know what the file will be called with Chrome, but it should have a similar settings file. Deleting it will cause the window settings to revert to default on restarting the program.
When I click on Analyze to open the Analysis Board, when using Google Chrome browser, the window is a few pixels too narrow. This causes the controls (game history, rewind buttons, etc.) to wrap under the board so they are invisible until I enlarge the window slightly. This also occurs with Safari - but not with IE8 or Firefox.
Is this a bug in Chrome and Safari - or chess.com? Or is there a setting that controls it?
