Recently, Album Art Downloader has become completely unusable for me.
When I just start AAD, it may happen that every bit of UI (windows, other programs, everything) but the mouse pointer freezes. After 4 seconds of being able to move the pointer around, it also freezes, my screens go to black and several seconds later I get the message that my display driver has stopped responding but has succesfully recovered.
The same sometimes happens when I use the file browser to search for files, but the absolute killer is trying to download album art for several albums. That is an absolute freezefest, with my display driver stopping for 10 seconds with 2 seconds of usable interaction time in between until I've either exited every last window of AAD or AAD finishes all its actions.
Although I am completely baffled as to how any application can have such a debilitating effect on my OS, I would be satisfied with this specific problem going away (as I do love the awesome functionality of AAD!).
No other application shows similar behaviour and apart from when using AAD, the display driver message is extremely rare for me.
