Cannot open new window under Vista !!
I was experiencing for some time a quite strange effect on my no so old installation of Windows Vista. After some dyas of usage without any reboot I sometime was unable to open any new window, it could be an explorer, internet explorer 7 tab, a menu of tray icon, and this without any error message. I first thought it was an issue with the video driver, but after too much annoyance I searched the web and found a post "Max Num. of Open Windows under XP/2003/VISTA - Resolved !' explaining the issue and a possible fix.
