Vista - IE7 problem

I hope I am in the correct place, but I'm sure someone will tell me if I am not!.
Using Vista Home Premium (preinstalled on Dell laptop). When clicking on the down arrow at the end of the URL / address box in IE7, instead of displaying the list of visited URLs an error message stating "application has created an error which cannot be handled"

Hi Jim,

First, go to tools/Internet options/general tab.
Click on delete browsing history and delete history, cookies and temp files.
Check if you have still problems.
If yes, close IE, click on Start/programs/accessories/system tools and open IE7 without addons from there.
If IE7 works fine, then the fault comes from an addon and you have to find which one is causing the problem.
Then if the problem still occurs, logon on a different account and check.
If no results, then reset IE (you will loose your passwords, config, etc..)
Tools/Internet options/advanced tab/reset.

Hope it helps.

Many thanks for your assistance. I am sorrynot to respond faster, but have been away for the weekend. Your solution fixed my problems and all is now AOK.
Once again many thanks Jim
