When you hear the 'ding', is there also an error message displayed into the status window?

The right-click menu is mainly controlled by the popups menu, default filename popups.ini, and can also have scripting which appends extra items to it.

It's possible that popups.ini or another menu file was damaged during the BSOD. This should hunt in the folder where mirc.ini is located, looking there or in subfolders for the default name.

Code:
//noop $findfile($mircdir,popups.ini,0,9,echo -a $asctime($file($1-).mtime) $1- )

And this is the file mirc.ini is currently looking for. Any path is relative to the folder where mirc.ini is located.

Code:
//echo -a => $readini($mircini,pfiles,n3)


If you find a good copy of popups.ini and copy it where mirc is looking for it, you should be good to go.
