Thank you Jan

This answers my first question. I was aware of the limits of 32-bit OS
but thought it was larger than 2.1GB. I obviously have more memory
available which I thought would have at least some impact as WinXP 32
bit can adress 4GB.

I think there are possibilities to force Windows XP to load processes
during the boot-process to upper memory in a better fashion, ie the
/3GB parameter in boot.ini but would like an advice by someone more
experienced before I start experimenting.

Now waiting for information about Stata 12 as it seems to use memory
differently than previous version.

Regards

Roland Andersson
