STL options not saving in SW2009 SP1?

Can someone else verify this please. Save a part as an stlfile, click on the options button, select custom settings, changethe sliders, try to click OK. On my system the OK doesn't function.The only way to get out of it is to hit cancel.

If this is a bug it needs sorting very urgently for SP2 please,anything that affects export is critical. Then again it might be mysystem!SolidworksParts And Features
