I am having a weird bug with properties sometimes.
If i do properties from an explorer-managed part on a link(such as the quick launch or the desktop) and choose "find target", it opens a new dopus window as i want, but it somehow locks the property window(i can not close it anymore). It usually disappears(the property window) after some time, or if i close explorer, but that's pretty weird.
(Usually after 20-30s)
Apparently the bug indeed comes from explorer and so there is not much that can be done or so.
Now this might not be related to dopus at all but... If anyone knows how to add a context menu entry to .lnk files to open the containing directory i'd love to hear about it:)
Use either of those on the LNK filetype. Using OpenContainer.exe instead of the Opus command would give you something that works everywhere, but if you just want it within Opus then you can use the built-in command to avoid dealing with the extra exe.
