Here is a brief summary of the more annoying bugs fixed from V1.2 to Version 2.
On some systems (especially accelerated A1200 systems) the program would freeze or perform strange things when selecting the 'blend in/out' gadgets in Compose, or similar gadgets in Crop. Moving the mouse while typing in a number gadget was also bad! This strange bug was a side effect of some strange gadtools gadget behaviour, and has now been fixed.
Another bug caused strange things to happen if you tried to use magnify within compose and/or crop. This has also been fixed.
The button to select simple/smooth scale tended to have little impact on whether the program decided to simple or smooth scale your image (1.2). Fixed in 1.2a
For some reason, the BMP.gio in V1.2 would save images that were 'slanted' when loaded into certain PC applications. This has been fixed as of V1.2a.
A field in the IFF Deep gio was found to be corrupt. This does not affect Photogenics (it does not read that field), but may cause problems with other programs that accept IFF Deep files. Fixed in 2.0
