We've had the odd report of problems, but so far have never received an ABI
file that trev couldn't accurately display (that the ABI software could).
Could you please uuencode and email me a representative set of the problem
traces? We can then try to find and fix the problem. I don't think we've
got a hope in fixing them without the traces to play with.

I've seen this for edited traces. It appears that editing on the ABI
software writes out a slightly different format ABI file, that we cannot
understand. Is this likely to be a problem?

I've never heard of these. It'd definitely be good to see the traces.

Is this really the case - that trev displaying to a Sun X server works
differently than to a Mac X server? Even when running the same trev binary?
If so, which is the system that displays wrongly. It sounds like an X
server bug, as both X servers should display identically and trev doesn't
"know" where it's display is.
