GIF's!

All I want is a 2-frame blinking graphic without using Flash, which bogs down most of the PC's they use here. I made three identical animations, each one looking like a blinking LED. One of them, a green one works just fine. But the other two, a caution yellow and a plain blue, look great in the Windows preview but turn out white with a thin outline of the original color when run in Lectora. Both the lectora preview and the lectora-created .exe file have this issue. Ultimately, it will be a SCORM course but I have no reason to believe it'll work any better there. Any ideas? I created the graphics in Adobe Illustrator and the animations in Photoshop.
