no... it's my fault on this one ;) the problem that i ran into was simply
running out of memory... blackbox had around (i'm guessing) 9k-10k pixmaps
stored in the X server... and we're not talking about 2 and 3k
pixmaps... some of them are very large (especially if you run netscape or
maximize applications)

the timeout is set in .blackboxrc under session.cacheLife... it takes an
integer which it interprets into minutes to wait before purging it's cache
of unused pixmaps... setting it low reduces the problem of the
(EEK) bloat, but it doesn't completely correct it... if you change styles
enough you could probably still bring your box to its knees just as i
did...
another solution is telling the new pixmap cache to behave like the old
cache and set session.cacheLife to zero, which tells blackbox to not wait,
and purge unused pixmaps immediately
