Hi...
I was trying to write down precisely what i did to reproduce the bug... and at first didn't reproduced... but now I understand more what the problem is...
In fact LSE isn't killed by Duplicate Cleaner... but sometimes DC launches explorer.exe in 32 bit mode, when no instance is present, and then even exploring by "my computer" icon, the 32bit instance is used.... And LSE isn't activated on the 32bit instance of explorer.exe ...
So I don't know how LSE attach to exporer.exe, but if possible it should attach to both 64 and 32 bit modes... Also, DC shouldn't launch 32bit explorer...
in order to reproduce, you can monitor with task manager the instances of explorer.exe. there is always one instance 64bit + when i browse directories an other instance...
If i close every windows then only one explorer is present and in Duplicate cleaner (and probably other 32bit programs) I use the fuction to show me the file in its directory, then it opens explorer in 32bit mode.
the command-lines visible in task manager are :
for the always present :
explorer.exe - explorer.exe
for the standard browser :
explorer.exe - "C:\Windows\Explorer.exe" /separate,/idlist,:49384:3644,::{20D04FE0-3AEA-1069-A2D8-08002B30309D}
for the DC one :
explorer.exe *32 - "C:\Windows\System32\explorer.exe" /e,/select,"H:\Images\image.jpg"
