2007-Nov-2 UPDATE Dick Hollenbeck <dick@softplc.com>
================================================================================
+ pcbnew
fixed a crashing bug which happened if you "dragged" a module with
tracks. Then deleted one of the pad connected tracks, then deleted the
next track attached to the first one. Memory was being corrupted because
PcbGeneralLocate() and display was not being called on the 2nd track to
be deleted because the m_Flags test:
bool ItemFree = (GetCurItem()==0 || GetCurItem()->m_Flags==0);
was returning false. Solution was to SetCurItem(NULL) after deleting a
TRACK. This makes sense, SetCurItem() is used for designating a "selected"
item, and a deleted TRACK is not even in the BOARD anymore and should not
be selected or selectable. I think this bug may have been causing spurious
crashes for the last couple of months.
