Hi!

If you have too many iso-evaluations, the message pane goes "blank" after
the first few ones, the "time to parse"-Box in the lower left statusbar
shows weird things (15388d 11h 41m 37s f.e.), and if you try another render,
the render window disappears and won't come back until a restart.
In addition: If you try to stop the "render" while Pov displays the Messages
(evalutations), Pov crashes (if you stop while the message pane is already
blank -> page fault) or does not react at all.

It may well be, that this occurs with other warnings, too, I didn't test
that.
