When opening Solidworks 2009 and earlier files with 2010 SP2.1, I can't save the part as an new 2010 file. Clicking the "Save " button does nothing. and doing "Save As" brings up the dialog box but still does not save the file. Previous version of Solidworks did the older file convert and save automaticlly, is this not possible in 2010?
