If you happen one day to be working in the old version 10 of a Concordance database that you're accessing through VM Ware you many have a problem with the image viewer. It will be open, but will not display on your screen because it's set to go to a second monitor on your regular PC.
Solve this problem by pressing the CTRL + ALT + DELETE option at the top of the VM ware screen. Then right click on the image viewer and select Maximize. This trick should work for other applications that you have the same problem with. Thanks to my colleague Roman for this tip!
