I have drop-down list on a web form and when I select an item from it using the mouse in IE8 it gives me a pop-up blocker error message at the top of the page ("Pop -up blocked. To see this pop-up or additional options click here...)
I can select items from it using the up and down arrows on the keyboard but the above occurs when I use the mouse. It doesn't happen in Firefox.
Any help would be appreciated.
Edit:I have tested the site in IE Tester and when I load it into IE 8 there it is OK so it must be an problem exclusive IE8 my PC.
