I seem to be having a similar problem with MM 2.3. If I try to set break points on anything from "Mere Mortals Framework Windows Forms 2005.dll" the breakpoint does not set. I get a empty red circle with error info: "The break point will not currently be hit. No symbols have been loaded for this document."

I went to Debug->Windows->Modules to check things out. The symbol status was "Cannot find or open the PDB file." I tried to manually load the "Mere Mortals Framework Windows Forms 2005.pdb" file and got the error "The symbol file Mere Mortals Framework Windows Forms 2005.pdb does not match the module."

The symbol status for the main MM dll, and the interfaces dll have "Symbols loaded.". However, the Automation dll also has "Cannot find or open the PDB file."

I am new to .NET and VSS so I am not familiar with common problems. Does this mean that I need to rebuild the MM Windows Forms project? Or is there another way?
