I used to have this problem at some point previously, but then it appeared to go away, and now that I've just updated to 6.0 beta 4, it's come back again:
I place a patch, click extract:
Patch shows up in photoshop just fine, but the dialog box from pano2vr (see image in link below) hangs at 99% for about 30 seconds, preventing me from saving the file in photoshop until pano2vr releases the file.
I am able to edit the patch while I'm waiting to be able to save, so it seems like pano2vr is just taking its time releasing it?
