Transparency doesn't work here neither. My laptop is 9 months old
it should work fine on a recent system imo! I'll have to add more memory i guess, only got 512. Everything goes fast except navigating trough folders. And i might guess the problem: IndexSearcher.exe fails constantly. I guess this is the program which keeps the fileindex of your hdd and controls the search to folders etc. Because of the fail I guess it has to search manually which takes longer. I'll ask microsoft about this.
