With my Dell dimension 2400 while using IE I am having problems connecting to links within a web site, sometimes.  For example, today while shopping for tickets for a Broadway play I wanted to view the theatre seating arrangement.  Clicking on that link gave me a "plunk" sound, a small 1" x 1"  box with a red X over a web-looking page w/ yellow box within, etc..  The web page that popped up was addressed http://www.buy.com/ and an otherwise blank page.  Further while seeking on-line chat help from Dell Support, when clicking on the "submit" button I got the same thing initially and then a page titled "Blank Page - Eastern Oregon Net" (my ISP) and a web address "about:blank".   This situation has been going on for only about the past week.  I haven't a clue what to do to remedy this situation.  Help!  For what it is worth I use Trend Micro PC-cillin Internet Security w/ regular updates, Spybot Search & Destroy and Ad-aware ckecks.
