URL protocol handler not opening the forms in VS when clicked.

Hello,

I have 2 related ongoing issues.

1>I had clicked yes to make VS as default for opening form control opener, so I do not get the pop any longer. Where can i change this default so as to get the pop up back.

2>When i click below form control, the VS opens but it does not open the form & control (its not a runtime) so definitely it should open the form & control. It was working earlier like month ago. Have rebooted the VS.

Thanks

Mav.
