When I open the New Mail filter set (run when New Mail open, the
WINRULES.PMC file) in Pegasus, the vertical scrollbar doesn't work properly
until the window is resized (each time).
This is the only filter set where the list of my filters is long enough to
take up more than a window's length, but the bug appears to be there for
(local) filter sets.
I wonder if others with long filter sets can replicate it?
If your filter set is relatively short, resize the window so it's shorter
than the list, close, reopen that filter set.
