Image gallery transition bugs

Hi.
Basicaly I’m making this image gallery to help improve my as3 skills, using the idea from the minus.dk image viewer clone thing. But there seem to be tons of bugs that I have no idea how to fix or even the cause of the problems. If you could help with the problems it would be greatly appreciated!

Images (I got all the images from www.sxc.hu, if anybody wants Il post a list of the names of the images and the username)

Bugs:

  1. When the thumbs first load, for some reason some of the fade tweens stop halfway or don’t even start at all. Leaving the thumb transparent.
  2. When you roll over/out of the thumbs sometimes they act weirdly, the transitions don’t go the they are suppose to?
  3. The preloader for the images that should be a orange box on the thumb that expands to fill the thumb as the image loads, but for some reason it doesn’t appear at all except in the flash download simulation thing.
  4. Once the image does load, the tween for the mask of the image sometimes acts weird (can’t really explain) or stops halfway? Same thing goes for the transition for when you click on the image to go fullscreen.

Thats what Ive got so far… any ideas? All of them involve weird transitions, so could I be doing something wrong with the Tween class?

Anyway please help!

thanks.
