I have trouble adding a Viewer control to my Winforms User Control in VS2005.
When I drag it from the toolbox, I get a stack dump in the designer view, showing "Exception: Method not found: 'DTI .... ScaleCommand.Process( ... )".
I finally managed to resolve this (as suggested by another post that had no reply) by removing the ImageMan component from the form, removing it from the toolbox, and removing all project references, before adding them all again.
However, the control displays this stack dump again in the designer after a short while.
I have installed this product under a trial licence on Windows XP.
