- Hmm, probably did a "public screen" swap or something that pinged the RTG/EGS
- drivers... probably won't stay there for long. Soon as the program does a
- blitter or copper function, poof. It'll probably disappear again.

-
- A bug of course. Also, keep in mind that our software defaults to
- interlace, which begot the 320x200 animation into the size of a QuickTime
- size clip. :) You've discovered the workaround however.

- Theoretically, it may work, but be aware that AnimLab does not save
- to any of the HAM formats, at least officially. Let me know what the results
- are after your experiments.
-
- Keep in mind that we have very little use for the HAM modes, other than
- displaying the images. You can't use text, text wipes and most of the
- page wipes do not function well in HAM. Therefore our support for HAM is
- limited.

-
- It works because AnimLab's 32I format removes every other scanline. Careful
- about making the animation playback too slow. Missing scanlines will become
- more apparent at 20 fps or slower.
