IE and Firefox differences : Multiple selections in List box of Qlikview Reports

[#1]

Hello Experts,

I have seen a difference when an item is selected from the list boxes of qlikview report when the report is browsed through IE and firefox.

In IE, 

I could not select multiple items say 20 of them by dragging the scroll bar.

In Firefox.

I could select any number of items by dragging the scroll bar from the selection box

This seems wierd to me....any idea folks ?

this might be a stupid question but:P

did you try dragging + Ctrl button?

Yes i did.

This does work in mozilla but not in IE.
