"Class already exists" Problem

Hi,

I have a problem when I try to access a DLL I have created. Basically I have
an application which uses a number of custom DLLs, I needed to amend one of
the DLLs, so I removed the specific Reference from the application, amended
and rebuild the DLL and then added the reference back into the application.
There was no need to amend the applications code as this was a very minor
change.

When I run the application I get the following:
"An unhandled exception of type 'System.ComponentModel.Win32Exception'
occurred in system.windows.forms.dll

Additional information: Class already exists"

I have created a new project and referenced this amended DLL and it works
fine.

If anyone has any ideas/suggestions it would be greatly appreciated.

Thanks in advance.
J
