I have tried to reproduce the problem but did not see any problems, right-click dragging a .TTF file from the Fonts folder in Everything to the Windows desktop.
I can't think how a ShellExecute hook would get involved in a file copy or move either, unless ShellExecute or ShellExecuteEx is being used to launch the copy, which seems unusual.
Is there any more information you could give us about this? Or more detailed steps on what to do to trigger the crash?
Have to admit that after complete uninstall, and then reinstall of DOpus Light 12.30 I can't reproduce it anymore.
Nothing changed in the system (1 day ago). What can I say: it seemed related since disabling only DOpus ShellExes I couldn't reproduce it anymore, and rehappened enabling them again...
I did read the thread on the Dopus forum and now I'm a little confused ...
My current understanding is that you (@hexaae) reported this to @void, who posted your solution on the Everything forum.
But that doesn't explain why it is discussed here instead of the Dopus forum.
I am missing something ( beside a braincell or two ) ...
