I’ve got one bug to report.
The option to switch to “Frame Number” instead of time codes in the “Preferences” menu is broken. Switching to time codes does nothing. To change to frame numbers, one needs to open “Project Settings” and make the switch there. I don’t mind Topaz moving the ability to a different menu, but any settings that are duplicated between “Project Settings” and “Preferences” should have the same effect when changed.
There was originally a second bug, related to whether Topaz produces frames or .MOV files as preview options, but my install has switched from MOV (which I did not want) back to PNG (which I did). I’m not sure why, but it’s not doing the thing I didn’t like any longer.
