I'm having an issue with a RadGrid not displaying right-click context menus in IE. Specifically, when choosing the auto-generated "Add New Item" button, the editor area (which opens in an iframe within the grid) does not allow me to right-click to open a Cut/Copy/Paste/etc context menu. This issue only occurs for me under IE, right-clicking generates a context menu in both Chrome and Firefox. I'm also not using any custom context menus and there is nothing in the code behind that should be affecting this. I'm wondering if there is a known solution to this or if the problem is could be caused by certain settings on the RadGrid or MasterTable?
