Karl,

This ties in with my experience. Using Xp Pro I find that every so often I
have to shut down PS because, even with all previous images deleted, it
becomes pathetically slow to handle another one. After closing PS and then
opening the new file, everything works fast again - for a while.
I'm just trying Picture Window Pro, but it would take some getting used to I
fear.

Note that Photoshop does its own internal memory managment EVEN when it is
running on a platform like Windows XP which does a better job of memory mgmt
than Photoshop can.  This is because PS comes from the old AppleOs world
where if you let the OS do your mem-mgmt, you were pretty much dead in the
water.

As a result, unless you start PS with nothing else running, you will
actually be unable to access the full amount of memory you have.
Furthermore, if you do start to hit real-memory boundary limitations, the
swapping algorithms in PS will 'outthink' the virtual memory in Windows and
your performance will go into the toilet.
