Can I use HandyGraph 2.1 to edit graphs in Word which I made with HandyGraph 1.1?
Unfortunately no. HandyGraph 1.1 only worked inside Word and created graphs that were collections of Word drawing objects (lines and text boxes). This was fast and convenient but was limited to Word and its drawing capabilities. Starting with version 2.0 HandyGraph became a standalone program the creates images that can be saved to file for editing later. An image can be exported (as a graphics file or using the clipboard) for use in Word or any program that accepts images.
