- Ummm... this does NOT explain why CPUBlit prevents rainbow trailers the first
- time I run Term, then quit it, and does not prevent them when I run Term again.
- This is probably NOT a problem with CPUBlit. Yes, I agree that CPUBlit is not
- a cure-all. However, it worked fine before. Why is it suddenly working
- sometimes with Term and not others? This sounds rather suspicious to me.
- I've sent you email more explicitly describing what's going on. Maybe you can
- make use of it.

- As you yourself said to me in private email, "faster layout" only works under
- Amigados 3.0... and incidentally, I tried it on an Amiga 3000 running a beta of
- 3.0, and "faster layout" does work -- the scrolling is slightly faster, there
- are no rainbow trailers, BUT the dripens get screwed up, so the embossed 3-D
- look of the beveled boxes and gadgets disappears. Weird.

- Not everybody can afford to get rid of his Amiga 3000 and buy a 4000. Besides,
- the blitter in the 4000 is essentially unchanged. Granted, chip bandwidth has
- improved because of AGA. But I find it hard to believe that The cure-all is
- AGA. As I said, if the CPUBlit hack worked before, it should work now.
- Something is amiss.
