I double-clicked to open a zip file and dragged the contents out to my Desktop. As the contents were transferring, I closed the lister window and DOpus crashed.
Edit: This crash occurred on the following DOpus version:
Directory Opus Pro 10.2.0.9 (4771) x64
OS 6.1 (B:7601 P:2 T:1) SP 1.0 "Service Pack 1"
Confirmed... I've sent in a crash report and referenced this thread.
Also noticed when first trying to test... that when I opened a zip file located directly at the root of one of my custom libraries and tried to drag and drop one of the files in there to the desktop, the drop animation says Opus wanted to ''Create link in desktop" instead of "Copy to". Dragging from the same file opened from the physical drive location instead of the library path shows the correct "Copy to" drop animation. More importantly though... the drag and drop from the zip under the library path doesn't actually do anything (i.e. it doesn't even create the link).
(Update: This has been fixed for the next release.)
