Sorry; you're right: ggiSetMode() doesn't return.

Profiling Timer Expired

There's a delay between the last debug message and the SIGPROF; it
varies between
about one and several seconds (I think that I had it running for over a
minute once).

I'm not sure where the SIGPROF comes from, however...

I thought that they should be used for minimum/preferred size?


Thanks for your help,
