We have not encountered such issue so far and it seems to be very strange indeed. I tested it with a simple contextmenu by setting its NavigateUrl
property but it is working as expected from my side (the page opens on the first click of the menu item). Can you clarify the version of the controls that you are using? I would also suggest that you open a support ticket and send us a simplified runnable page that we could test locally and help you out.
