Some, though not all GIF images do not display corretly. This is hard to
discribe. I have included a gif file attachment which demonstrates the problem.

Reproducible: Sometimes
Steps to Reproduce:
1.Surf a page with a GIF which does not display correctly. (See my Gif attachment.)

Actual Results:  
Gifs display incorrectly.

Expected Results:  
Proper GIF display.

Note: I believe some GIFs display correctly while others do not. My knowledge of
the Gif image file format is too limited to know what image file conditions or
settings used to save the GIF may cause the image to display incorrectly. I also
am unsure if this issue is solely with Mozilla 1.7rc2 or with an incompatibility
between Mac OS 10.3.4 since the GIF image issue occured shortly after upgrading
to 10.3.4. I also believe the Gif issue may be rekated the the incorrect display
of icons in the default Mozilla skin on OS X.

I am closing this bug as worksforme. The display problem with some GIFs and UI
theme icons appers to have been fixed with Mozilla 1.7RC3. I will reopen if I
encounter this issue agin in the future.
