I think you might be right, but I would like say that the following error is sometimes very hard to create actually I had to first click on directory opus app on desktop then on my computer icon (which have default action to open with dopus)
So I think the error is because of too many attempts to launch the dopus shell action while opening exact same folder. On another windows installation I had before there was similar error but that one said about "error sending command to desktop" something similar and it was more common
Of course if I just wait each boot until dopus unlocks shell then error will never appear.
That all shell locking is happening when explorer replacement is on
Like I said before when Explorer replacement is off and even if dopus is an item in shell so it is in context menu of every folder drives and special system folders still it wont lock up the system and dopus will actually come up on right away just like explorer when desktop appears and I right click explorer then select open in directory opus! no shell locking at all
About windows:
Because of this slow startup problems I got rid of old windows installation that had all programs I need and all mods for better experience and easier access to stuff
I installed new fresh install of windows xp, but not the original unmoded windows, becuase I added few programs like unlocker and modded dlls and tweaked its settings the way I like with nlite to make it look like windows 7 icons)
Ever since installing that "basic" thing I didn't do pretty much with it, because I'm careful and want the best performance out of it while having installed all programs and still be without cluster, so I even do a backup with acronis before installing anything so I can just step back anytime, its the only way to be sure of complete removal of junk files dopus and other program leave behind after uninstalling, even revo uninstaller can't remove everything unless you track installation with it, but that will only take care of files and registry that were made during install not those the program does after install.
Well dopus did not work on this fresh install of a bit modded windows so I will try Installing another virtual windows in vmware, but this time it will be official unmodded windows. If that will help then I will try to find out what is causing the problem.
Also my confing doesn't seem to be causing anything as same is happening with this current modded version of windows in vmware, same just like the hosting windows which had dopus installed yesterday and got restored, because of opus causing problems and wont install it again on host windows until it will work without locking up shell, instead I will do all the testing in vmware like I did with rest of programs ever since format.
Re installation doesn't work
default config doesn't work
explorer replacement off works, but cant work without it
Older versions of dopus seemed to work at first better, but at end both 9.1 and 8.22 do same thing like 10
Another file managers that also can integrate as replacement do not have any shell locking problems, but they are not even nearly as good as dopus.
Only thing I can do now is try that official xp sp3 fresh install in vmware with nothing but dopus
