Hi Billz
A quick google search found this Increase the size of Windows Calculator however "I", and Vista Forums do not Condone this method And can not be held responsible for any form of system corruption or any other such damage
That utility makes everything temporarily bigger, not just Calc. It's great for presentations and I thought I'd mention it in case it helps you too, even though it's not a direct answer to your query.
Thanks for the tips,guys. I looed at your link,ripbox and it looks like the cure is worse than the disease!LOL Think I'll pass. Haven't checked zoomit yet.
