Can't See Folder's Name When Desktop Composition Is EnableE

after that problem all the pictures were gone i posted it here and couple of forum and nobody was able to know the cause, my computer was apparently clean... but my pictures are gone, i can recover it with any recovery software because thy are kind of marked as deleted or hidden" in such a way that can not be just simply be undone, i must recover one by one. in order to keep the hdd untouched, i had to buy another one (i dont want to open a post just for asking the temperature but is 41-48celcius normal? i know its normal but the hdd sometimes reach the 48 49 and stay there for long minutes then cold down again, the old hdd had a narrow range 40-43)now continuing with the header. since i have a new hdd i had to install Windows 7 and i decide to give it a try to the aero and desktop composition stuffs BUT immediately i remembered that I used to not use by just one thing. use the computer with several windows opened, when i have to switch to another window i put the cursor in the taskbar and i get the list of the opened windows, but when the aero o desktop compositor are enabled i only see the thumbnails, pretty nice BUT just that, cute but awful since does not have folder names (not untill 2 seconds witht the cursor over one thumbnail)
