I very recently downloaded the demo, bought the full version, installed the full version, then deleted the installed demo.
When I try to save or export anything, or even create a directory via file dialog, it appears in the relevant file dialog, but not in the Operating System's directory tree. I can close the program, re-open it, and all my files can be reloaded just fine, but I cannot, for example, find a file and copy it, move it, email it, any of that. The files and directories don't appear in the open windows where they should.
It's as though QCAD can see everything it has done, but Windows can't see anything QCAD has done.
