Cited gif image is not displayed correctly.  Two rectangular blocks of the image
are not visible in most animated frames.

Yep. I can see it. The frames that ask for the
'backgrd' fill instead of 'leave as is' fill for the
transparent areas seem to be the trouble.

This is a bug. If you would like to know of a work around
until the fix can be checked in, you could change the 'background' fill
to 'leave as is" and the gif displays well...except for one
frame that needs to clean up a portion of the animating orbit.

I think this should be fixed. 
It worked in 4.x. 

I don't see anything that could cause this bug to show up,
but I have a feeling a bug was fixed somewhere else that uncovered
this one.

I'm testing a fix now.
-P
fix not good.
Moving bug to m16.

Well, if you look at the 06/01/00 GIF attachment you can see an error appearing
on the 3rd frame ("JBuilder Trial 3.5") at the right side of the picture of the
monitor. The GIF uses the "Leave as is" option on the first control header, but
in all the following frames the delay headers specify remove by "background".

It's also strange enough that the GIF paint only one time the monitor border (in
the 1st frame). In the following frames (the 2nd and the 3rd for example) should
paint only a rectangular box inside the monitor picture (where no rendering
errors seems to appear).
Let me also say something *maybe* has to do with a bad handling of the PNG image
trasparency. It sports some areas with the same behaviour of PNG not completely
transparent areas.
It courious that this behaviour disabbear if the first GIF frame is complitly
opaque.
