It seems someone invoked irony using the following comment in the code:
/* this search is guaranteed to succeed */
SearchObjectByLocation (LINE_TYPE | RATLINE_TYPE, &ptr1,
&ptrtmp, &ptr3,
Crosshair.AttachedLine.Point1.X,
Crosshair.AttachedLine.Point1.Y, 0);
BANG. (Remember kids.. never be smug about what will / won't succeed!)
Actually, its not the search's fault.. the Crosshair.AttachedLine stuff
is probably not getting set properly.
SO - what is the "CORRECT" behaviour for "Only names" mode.. allow line
creation, or deny it completely? This will probably alter where / how we
fix this.
