First things first: 3.3 is a beautiful piece of work, it's brought me many hours of joy in between my days of cramming and mindless homeworking
Now, on to the annoying bugs: I seem to be having trouble getting FRED 2005-12-22 to do texture replacements without crashing thereafter on save. I thought the 2006 build might have fixed this, but much to my dismay, the 2006 build buries me with what looks like a hundred or so errors in ship.tbl on load (it seems to dislike the $type, $animation, and +relative_angle tags). When 2006 finishes loading, the main panel - the one where ships and such would normally be, is not rendered and the mouse disappears.
Now, obviously these are not TBP issues so much as SCP issues, but I figured you folks have seen this plenty and would have some ideas as to the culprit.
