An animation problem this time...

Hi it's the newb again...the dialog loads 🙂 Anyway, everytime I want to bring up a picture for an animation set it says "Exception of class...Application must shut down"

I think I saw a topic on this problem b4 but I can't find it...

Can you help? :frown:

------------------
Thank you.

Well, I think it only happens because there's 1 frame in the animation...but it still doesn't make sence...

------------------
Thank you.
