Quote from Scataphagos:
I sized a window for IE9 to be smaller than to fill the entire monitor... when I restarted the browser, my sizing is ignored. (Fresh install of W7, no other apps installed.)
Hmm... may be the issue is with IE9 not Windows 7. I am only using IE8 in Windows 7 64-bit Ultimate. I don't have this issue.
What I observed is... if you have multiple instances of IE running, it will take the last one exited to retain the size/position settings. e.g. If you have 3 different instances of IEs. You change the size/position on IE#3 only but IE#1 and #2 are still running. You exit IE#3 and restart (while IE#1 and IE #2 are still running)... the new IE#3 will take the new size/position. However, if you exit IE#3, and then exit IE#2 #1 (whose size/position have not been changed), next time you start IE it will retain the size/position from IE#1 setting.
