When opening mulitple files, it opens in new window rather then new tab

[cjstuff]

In the previous version of DEV C++ (BloodShed), when I opened multiple files, they used to get open in a new tab in the same window, but in this version of DEV C++, they always open in a new instance (window). Can someone kindly fix this issue?

PS: I love DEV C++, don't want to move to some other IDE.

Thanks
