...on a single machine that represents the degenerate worst case. Sorry, but in
my scores of OS/2 installs, I've never run into anything quite that
pathetic, and if I did I wouldn't hesitate to replace the unsupported video
card or at least turn off full window dragging. In a previous message I
asserted that any program that runs at an elevated priority _must_ ensure
regular blocking, and that I viewed this as the most glaring flaw of OS/2's
priority scheme. It turns out that you've simply confirmed this with a
program that fails in precisely the way I described.
