Thanks TCS........
I use Zone Alarm Pro and turned off the ad-blocking function as you suggested but without achieving the desired result. Strangely, under the "Last Post" column on the Forum Home Page, a click on the user name calls up his/her profile. I briefly disabled Zone Alarm completely and lo-and-behold the "profile" button reappeared. I'm working on the assumption that I need to make a not entirely obvious adjustment somewhere deep in ZA.
Thanks again for pointing me in the right direction.
