How to generate a crash (or bug) report

I am trying to work with Soho notes (documents management: scanning, archieving, ....). I have a problem while using one functionality of this software: the mouse pointer becomes the spinning wheel with all the colors. After I have waited more than 5 mns like this I have to force Soho Notes to quit. The customer support for Soho asked me to send a crash report in order to help fixing the issue. Can somebody help on how to generate such report. Thanks in advance.
