Menu click event problem

I am currently working on Facets 5.01 extension implementations. It is the window application developed using  C# and .Net 4.0.

 

I have 3 modules and all have their own menu events and short cut keys for Open (Ctrl + O), Edit (Ctrl + E)  and Save(Ctrl + S). When deploying all 3 modules on Facets application, short cut keys are not working properly. When I click the Ctrl + O of third module to open its popup window but application is opening the first modules popup window which is not correct. The same error is happening while accessing from second module also.

 

Any help on this would be greatly appreciated.
