Question about text size when resolution is set at 72 pixels/inch...

Hi everyone. I know this question has been asked a million times before, so I hate to be a pest, but I've read through all the entries in the Memories that cover it, and I still can't figure out how to fix my text size, so I thought I'd ask and see if anyone has any other ideas on what I can try.

I'm using Photoshop 6, and my resolution is already set at 72 pixels/inch, but for some reason, I can never get my text big enough. I can barely see it! I've tried just about everything, and I'm getting really frustrated, so if anyone knows of a solution other than "change the resolution to 72 pixels/inch," I'd really appreciate your input. Thanks in advance. :)
