Sorry guys
This issue had comfirmed NOT caused by CCleaner or winapp
it caused by a program call "lingoes"
and crash problem is caused by flash
sorry to disturb you
----
I'm using XP SP3
Not sure if CCleaner cause the problem, but before I'm using the "clener" function to clean some files, the problem never happened.
If I open a file folder through a shortcut, in task manager, there will be a axtra explorer.exe, it should be close when I close the folder window, but it didn't, I have to manully close the second explorer.exe or I can't open a new window through a folder shortcut.
Here's the list that I was cleaned (I don't think clean these files will cause the problem)
Temporary Files
uTorrent More*
Cryptographic Services Traces*
Device Manager Cache XP*
Now I've uncheck "Launch Folder Windows in a Separate Process" in folder options, it only allow one explorer.exe, problem seens be solved, but if I check it again, the problem's back.
Maybe it's not the CClener's problem, just FYI.
