But it still behaves a bit strange on > undo: The next segment seems to start somewhere off canvas. 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. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)
