[PD] GUI overload

Oooh, aargh, exactly the same!

San Diego (Houston) we have a problem...Miller's sys_pollgui() fix is the only one I found that works, and perhaps we don't know why it works, but it works for me. Bear in mind I have 32x64+256=2304 GUI objects to update when the pattern changes on my sequencer, but I'm not entirely convinced that is the whole problem. The version I sent you (with all those GUI updates) worked fine it turned out, but the version I made of the sequencer to try to counteract this (with no GUI updates) - the performance patch with that still had the problem.

Since I now have both Pd versions - hacked vanilla and extended - is there any test I can carry out to determine what the issue might be?
