I just would give an update on this issue. In the last days my Dell Precision commenced to be usable.
The problems with Desktop/Task Bar explorer.exe were irrelevant.
BUT, I still got some problem with the separated explorer.exe (Cabinet Class) just the first time that I had to come back to control panel two times with a short interval to fix/change a parameter.
So I must confirm that the main reason for the current notebook usability is the replacement of explorer.exe for file management with Directory Opus. Otherwise I would quickly come back to unresponsiveness as I would have to use much more frequently than now the explorer.exe.
I am still wondering why the 2nd explorer waits for 45 seconds to close. I just made now a test on an XP SP3 and the second explorer used for file management closes >>immediately<< after the last window closes.
This seems a bug related to the problem I am reporting. Also I am still looking for a way to get the same behaviour on Windows 7.
