Dropdown dosent work after update to 2011.3

[Wendelstam]

Hi

I have used the following code for a while but after updating to 2011.3 from 2011.2.Sp1
The combox is not displaying the dropdown when clicked. Have reproduces the issue in a simple standalone webform and it seems as if the child controls (asp:DropDownList) is causing the issue somehow?

Any ideas about how I can fix this?

Thanks in advance
Johan

EDIT:
Updating to 2011 Q3 SP1 solved it. Dont know what caused it but it works after the service pack
