That is bad. I think I can see what is happening. I suspect that this
is a fairly hard race to hit - you must been unlucky:-(
I had an oops removing a bitmap a wee while ago, and I mentioned it on
this list, but I couldn't post a backtrace. I guess I was unlucky too
but I'm delighted to hear luck's not going to be an issue in the future :-)
Cheers,
John.
