Captivate 7 crashes when inserting an animated gif

Hey guys,

I upgraded to Adobe Captivate 7 and asked the same question in that forum, but I could really use your help. I want to insert some animated gifs, produced in Adobe Flash Action Script 3. Most of them import fine, but some of them cause Captivate 7 to crash while inserting. I exported them and the others with the following settings:

I'm not sure what the problem is since the settings were the same for all animations. The size didn't play a role either. I have to use the animated gifs and not flash, because we want to publish the project in HTML5 for web and devices.

I'd really appreciate your help!

Thanks

Nat
