If you're using Internet Explorer 8 (IE8) you may have experienced the "Connecting" message, either when first opening the browser or when opening a new tab. This has been my only real frustration with IE8, and I thought I'd found the fix... until it kept happening.
In a nutshell, sometimes when you open IE8, instead of showing your Home Page you'll see a blank, white page and the status message "Connecting". The round blue status icon is spinning away, and nothing ever appears. I've read a number of suggestions about the cause of and fixing the problem, but haven't found a definite answer that works every time.
A common belief is that an addon or toolbar (particularly Google) in Internet Explorer is not working correctly. You can try running IE8 without the addons by going to Start - All Programs - Accessories - System Tools - Internet Explorer (no addons).
Another attempt at a fix would be to open a command prompt as Administrator and type regsvr32 actxprxy.dll
Then restart the computer and try out Internet Explorer.
Or, you could do what I've been doing while waiting for Microsoft/Google/whomever to fix the problem - install and use Firefox 3.5 http://www.mozilla.com/en-US/
And, remove those toolbars!
