Whenever I customize Excel (add a button eg. run macro or record macro) and close excel it "forgets" the customization which is more annoying than spilling hot sauce in the eye... I've tried deleting Excel11.xlb and the Personal file and uninstalling Excel 2003 (including removing all regedit references to excel) but that doesn't help. Any ideas?

Also for some reason my standard paper size is set to letter and I want A4. Where do I change that permanently?
