Win 7 (32) / DOpus 11 Beta 11
When importing icon sets through the preferences dialog, DOpus stops responding and requires a restart. The icon set actually imports and is available after the restart.
I can't reproduce this using Opus 11.1 (x64) and the Star Ratings icon set.
Does it happen for you with all icon sets or just some?
It worked fine with your icon set, but locked up with various other sets (METRO, S DOX, Basic) from the Icons subforum.
I installed 11.1 and now have no problems. Not sure what was occurring with the last beta; may have been a reboot issue. Otherwise good to go!
