I think the key clue here is "When rebooting the PC, and restarting the application, the problem
disappears,
and all windows update reasonably synchronously." Short and easy answer I
believe is poor memory management by Win98.

Highly recommend Windows 2k

You will get a performance increase but how much is another question.
Expect minor increases in the ability to read and write to memory
which give you the impression that the computer "is faster".

Don't run TS Pro myself but with any increase in mhz, sec., etc.,
you'll see a performance boost.

Yes, with win2k, multi-monitor is significantly easier to install and
manage, IMHO.

I've always had a personal bias towards Matrox when it goes against
Appian Graphics. IMHO, Appian cards are too expensive for what they
offer and Matrox is a better video card company that has better R & D
and ultimately products.
Personally have not used the G200MMS card but have used a G400 32mb DH
from matrox and they are one of the sweetest dual monitor card so I
don't think you'll be disappointed by the G200MMS.

I build my own computers but I have always found Dell computers to be
solid computers. I recommend Dell to all my friends and users that
can not build their own computers if they can afford the extra premium
that Dell puts on it's computers.

WinNT and Win2k will be able to take advantage of SMP with more than
one processor but if your application can not take advantage of SMP,
it's basically useless but I have heard people directing specific
programs that can't take advantage of SMP to specific a cpu, but I run
a single cpu system so can not speak of it with great confidence.
LT> Anyone out there running AMD's Athlon?
Yes :-) Let's just say most of the techy people I know run AMD.
Intel has build a great brand name, which is the reason why people
still stay with Intel. Digression here but "Intel inside" isn't what
it use to be since AMD has been making some great chips.
Note: I'm more of a computer techy than a successful trader, for now
at least.
