Hi Mike,
This isn't strange behaviour if you're supporting a site that uses
huge powerpoint presentations. The marketting department at one of my
customers uses 200-300 slide powerpoint presentations which used to
hang Powerpoint on a fairly regular basis. By hang I mean totally
unresponsive to the extent of no longer refreshing the screen, dead.
We had a look at what was happening, and it was generally a single
runaway thread running at high priority.
Tried a bunch of things but what finally fixed the problem was
introducing CPU control, in this case Threadmaster. Not only were we
then not seeing instances of Powerpoint hogging a CPU, but Powerpoint
stopped hanging. Fixed most of our excel issues as well.
I'm very much of the opinion that some sort of CPU resource control
isn't just desirable, it's mandatory for system stability.
The commercial products from Appsense, Tricerat, Aurema (PS4) etc are
all a good deal more sophisticated than Threadmaster but I'd suggest
you run something, and in Threadmaster's case, the price is right
(free).
regards,
Rick
