Hi Neil,
	I don’t know why your systems would have started having problems in the last 48 hours.  Nonetheless, I suggest you try using the daily build instead of the production release.  The daily build uses a newer version of the Tk windowing toolkit that Chimera relies on to draw windows, handle scrolling, etc. and that newer version in particular has some fixes for bad scrolling behavior.  If the daily build fails to remedy the problem, try using Chimera’s Help→Report a Bug to make a bug report.  The bug report will include many details of your hardware and software setup that will help us investigate the problem.

We have two new identical systems that were running perfectly as recently as 48 hours ago, but now Chimera is constantly crashing whenever we do something as trivial as File>Open or if we attempt to save a map.
