File Association?

[skrath]

When one .c file is open in CodeBlocks, I am not able to open another .c file from the Windows Explorer (by double clicking on it) in a 2nd tab in the CodeBlocks IDE.
If I double click on the file, the simply CodeBlocks IDE comes into focus without opening the file.
In my Environment setting, I have multi-instances checked out; open in the same instance checked in.
Can anybody suggest a solution?
