After the very recent rude rhetoric from a certain user, I feel someone should mention that bug reports should not be posted in the support forum. Koolmoves has a specific routine for handling these and as our changelog clearly shows, Bob is on top of all reports sent to the correct place.
I don't think this is a bug. The action is _root.gotoAndStop(3). Swf frame 3 is not the same as key frame 3 because you are using tweens (6 actually). If you set tweens to zero, it should work.
I encountered a very strange thing in latest versions and I had to react.
A nested bttn won't react to gotoAndStop/Play!!Take a loot at the attached file.Stop action is on the 2nd and 3rd frame, not on first.
There is no bug at all.
Many KM users are doing the same mistake.
They use 6 tweens per keyframe (the default KM setting).
I told Bob several times to change that value to ZERO.
In your example there're 3 frames of 0.233 seconds (6 tweens).
In other words, any gotoAndStop(1...6) is a jump to the first frame.
