The compiler seems to crash when trying to compile the RailCaterpillarControllerGUI constructor. Any ideas why? I'm using 8.0.50727.867 (vsvista.050727-8600), boost-1.34.1

Try adding the argument placeholders to your bind call:

// cbToggleDeadZone should be called by widget's callback CBF_Callback callback( boost::bind( &RailCaterpillarControllerGUI::cbToggleDeadZone, this, _1, _2 ));

HTH / Johan

Of course, forgot the placeholders... Thanks! -- Daniel
