This problem may be caused by the following:
1. Problem with disposal method
2. Problem with the number of colors that can be displayed
1. Problem with disposal method
One of the properties that you can set for an image frame is "Disposal Method." Note that an animation may fail to display as intended on a browser if you set either of the following as the deletion method.
"Restore to Previous State"
"Not Defined"
Although to "Restore to Previous State" is a convenient deletion method, Netscape Navigator does not support it. If Netscape Navigator is being used to view your animation, the user will not see it as you intended.
When you set "Not Defined", the action performed will vary with the browser being used.

2. Problem with the number of colors that can be displayed
When a display that is set to only 256 colors is used to display an animation, the colors may not appear as you intended. To solve this problem:
Increase the number of display colors.
You can set this with "Screen Properties." For details, refer to your computer manual.
Reduce the number of colors used by the animation.
To do this, set each image frame to use the global palette. For details, refer to Using a global palette
