Nah man, that's not even ranting. There should be a built in equivilant to ms paint for macs....it's bush-league.
I was going to attempt to cope with Pixen, but the second I saw it couldn't even remember the colors I chose, I became a skeptic--if a program can't store 3 values--red, green, and blue--with out messing them up, that is really sad.
It didn't take long for me to start a search for an alternative when every color got fucked up after changing one color to another--damage I couldn't undo!

It's got a built-in feedback, so I typed up a big bug report and commenced to send, and I'm greeted by a nice error message.
-it sometimes can't undo things
-crashes always.....always
-closes windows when opening other ones....especially the palette window
