I am working with a GP add-in created in visual studio and deployed to the AddIns folder - note this is not originally my project. The add-in places a menu item on the Payables Batch Entry window's Additional menu to open a custom window. I changed a parameter's default state which is unrelated to the menu item. I then renamed the existing DLL in the AddIns folder and copied the newly built one in. When I view the Additional menu there are now two items for this window and both open the window.
Would you have any thoughts on why there are two menu items or perhaps have some direction of where I should continue investigating?
