well i have the same problem, sometimes Excel freezes, sometimes Outlook for no reason and not all the time. I never use (in general) more then 60% of the memory so it is not the memory. Pagefile is set to 300 MB in order that, if necessary, a dumpfile can be created. So far there is no indication that the pagefile is used since the pagefile can go up to 1000kb (that way i can see if pagefile needs expansion).
I have 4 gb of memory, but 8 gb would be best.
This is the fault of Vista, nothing else (as always). Vista consumes too much memory, NOT USED and to free memory one has to shutdown and restart (hate that).
Bottom line.....way too much bugs in Vista in general.
Vistax64 works not only in the 64-bit condition, also Office (and Outlook) still work in 32 bit environment.
It would be nicer if everything works x64 of course.....Maybe next century?
What i do not get is: how can one be one of the richest people in the world and deliver software, never good enough.
You must admit, the last 12 months there where more then enough patches to fix "this and that".
