Windows Server 2008 R2 -- Another Vista (Pig with a lipstick?)

For some reason, Windows Server 2008 R2 derives a sadistic pleasure in terminating non-MS applications when common Windows controls like File -> Open, File -> Save are being accessed. The most closest trace I found was the default location it was choosing like 'Favorites'. I reported this to Bugzilla (Mozilla) and they found out that the culprit was Windows and not Firefox.  Reported this to MS through forums. No responsible fix till now.
