.NET ShortcutKeys on ToolStripMenuItem in main Form doesn't work when other Form is active
<p>I have an application (.NET / C#) with a main Form and two optional tool/property Forms. The main Form has "Ctrl-S" set as ShortcutKeys for File->Save. When the main Form is active, Ctrl-S works fine, but when one of the other Forms is active it doesn't work. 
This setup in an application is so common, I'm sure there's a simple solution, but I just can't find it. </p>
