Captivate 7 crashes when inserting an animated gif

Hi guys,

new day different problems. I upgraded to Captivate 7 and want to insert some animated gifs. Some of them import fine, but I have two that cause Captivate 7 to crash on insert. I created them with Adobe flash and exported them 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 insert these animations as animated gifs, because we will publish the project in HTML5 for web and devices.

Thanks for all your help!
