Hi

I have come across this quite a lot when running and debugging PWS.  I
haven't been able to nail it down yet.  I have been wondering whether it
has something to do with Morphic dealing with debugging a multi-process
image; but that's just unfounded speculation :)

It doesn't just happen in the debugger, but also in other windows.  If it
gets annoying, I just restart the image, and it seems to fix itself.

cheers,

Russell
