Dear Sir:

In our product we use third party control, put third party control inside ext:Panel control. first we use ext.net 1.1 in our product. we have issue when it run in IE 10 environment. third party control can do drawings in the control. when it draw in the control the drawing is out alignment with cursor. So when upgrade our product to ext.net 2.4. and the issue is solve when we upgrade to ext.net 2.4, so it works in IE 10 now. But when we run the IE 11 the issue come back again. the drawing is out of alignment with cursor. always display in upper left of the cursor. Do you know what's the problem is? Why it is not work in IE 11?

Thanks

Holly
