Stumped.

I started up an old project that used to work and it recompiled w/ no errors. Now I'm getting the following error at runtime:

Compiler Error Message: CS0011: Referenced class 'OakLeaf.MM.Main.Web.UI.WebControls.mmButton' has base class or interface 'OakLeaf.MM.Main.Security.ImmSecurityBase' defined in an assembly that is not referenced. You must add a reference to assembly 'Mere Mortals Framework Interfaces'.

The Mere Mortals Framework Interfaces.dll is indeed referenced and I've removed it and added it back in and still no fun...

I also found this in the help file:
"Note: Due to a bug in Visual Studio .NET, there may be a few extra steps you need to take in order to add the controls to the Toolbox. Apparently VS .NET has difficulty loading controls from a DLL that references another DLL. However, we can fake it out, by attempting to add controls from the referenced DLL (Mere Mortals Framework Interfaces.dll) and then adding controls from the real DLL. If you run into this bug, perform the following command before step 6."

But I tried reinstalling the tools, yet that changed nothing...

Stumped, stumped, stumped...

Any suggestions would be appreciated.

TIA,
Chris.
