CRM 3.0 Click Event bug in system views

Hi ,
Does someone also had the same problem, that when i want to select a column to remove in the associated view of a entity (every view actually) i can't select it. I does not contain a green rectangle. I have the hand and the tool tip to click here, but when i click noting happens ?

Does someone knows anything that could cause this ?

Found the answer,
Add "about:blank" as trusted site in your tools - internet options - security - trusted site
