JJ- you're a bloody legend mate. Looks like i have changed the permissions in my blundering around, much like a bull in a china closet...
You're right too, that registry stuff does confuse me, and scares me!. Figure what i will do now is do a full back up- need to anyway- and then try and follow your instructions. Will be a big learning for me, and if i produce a large clusterf_ck at least i will be prepared to reinstall.
One last question before i head off into new territory... for my machine, what should i set as the minimum and maximum Pg File size (as the article says- 44 100 - their eg is an older machine right?)? Say 100 700, or more?
BTW commit charge right now is Total ~122MB, Limit ~260MB and Peak says ~168MB. So well under what it should be, just like you said.
Enjoy your sanga mate. I'd better get on with this, things seems to be hanging and starting to get worse. Will let you know
