SetFileInfo will unlock the file.  The attribute bits control this.  The
D bit is enabled to allow destroying, disabled to dissallow it.

I don't have my GS/OS manual here right now, but I am sure someone else
will help out.

You must be trying to use TaskMaster.  When I wrote an NDA (about two years
ago), you had to do a _FindControl and call _TrackControl with the handle
_FindControl returns.

You could do a _GetMouse and read screen memory directly based on the
return point.
