Run time Error Message with Pop up messages on 8.11

I am getting a runtime error message along with my pop up message(message form), which asks for user confirmation.

The runtime error message is :

" A Runtime Error has Occured.
Do you wish to Debug?

Line 5845
Error: Can't move focus to the control as it is invisible, not enabled, or of a type that does not accept the focus."

If I click the NO button, everything works fine.

Has something changed in 8.11 which is triggering this Runtime Error message?

This is an error in the webpage itself, not the business logic. This is typically a javascript error.

Could you tell us your browser version, etc?

We're using Internet Explorer, version 6.0.

Usually in these cases I have found that clearing the IE Disk Cache on the local computer will resolve this issue as well as other general slow performance issues that seem to be prominent with 8.11.

Try this first see if ti helps.
