I am developing a ProcessBook addin to aid in building standardised displays. It has a menu bar with entries for running a number of tools. It is built using C# in Visual Studio 2008 Professional.
When running it, it works fine at first but after a few minutes, although the menu still works, the addin stops responding to menu choices. I have set breakpoints in the menu event handlers and they stop being triggered after a few minutes.
Does anyone have any ideas what might be causing this?
