There have been a few people, including Big Frank, with problems with the colours of some objects in some of the frames of exported animated GIFs.
There was a problem with 8 bit animated GIFs in 1.0b when the number of colours used was less than 256, this was resolved in 1.0c.
There is a problem that was not resolved in 1.0c that occurs when animated GIFs use frames which are both hidden and used as background frames.
This can cause some colours on some frames in the animation to be incorrectly rendered.
There is a user workaround which completely fixes this problem.

In the frame gallery there is an option to select all frames, this is the button with the mouse pointer, depress this prior to the export of the animated GIF.

Any future releases of Xara X will feature a fix for this.
