Would that be this message?: http://www.mail-archive.com/wxhaskell-users@lists.sourceforge.net/msg00840.html I think that's done the trick! After I'd stared blankly at this for a while, the penny dropped: the fix, if I'm following this right, is to do the GUI update asynchronously (i.e. in a forkIO), _and_ to use a timer of the desired granularity, as above. This seems to work (though unfortunately also causes inconsistent updates violating a program invariant, a "freeHaskellFunctionPtr: not for me, guv!" error, and periodically a segmentation fault (I think this probably relates to combining concurrency and mutable variables, which I need to go fix next)).
