Vista - Monitor settings

I am hoping this will be a simple stupid problem....I set up my new system
and I am having a hard time adjusting the text on my monitor. I have set the
standard "view" (via view & text size) to what I want it on, however,
whenever I have a log in ID or password to type it is appearing on the
monitor in the smallest tiniest text possible...the text that appears on my
homepage is an appropriate size when viewing other things...it seems to
happen predominantly on my log in id's/passwords & on all of my
norton's/symantic's screens...it appears like it is typed in Arial 2pt or
3pt...my old eyes can't handle that! Please help....
