Not interfacing properly that is.
In Unity when you double-click a script, it should open up MonoDevelop and then go to that script.
In my MonoDevelop+Unity combo, it will always open a new instance of MonoDevelop and then open the project. I could have 5 MonoDevelops open, when it should only reference one. Yes, I synched my project w/ MonoDevelop, but this issue seems to be persistent. What’s causing it?
MonoDevelop 2.4
Unity 3.3.0f4
Windows 7 sp1 32-bit
I was having the same problem. I’m using 64 bit windows and the same versions of MonoDevelop and Unity as you.
Are you using the version of MonoDevelop stored in the Unity folder: “C:/Program Files/Unity/MonoDevelop”?
That version should sync properly and won’t open up multiple instances of MonoDevelop every time you click on a different script from the editor window.
Installing MonoDevelop separately and trying to sync doesn’t work as far as I can tell.
I hope that helps.
Just fixed the same problem with Unity 4.6.5 and Mono Develop 4.0.1 on Windows 8.1.
I noticed it started occuring in Unity 4.6.5 after I also installed Unity 5 on my PC. I manually pointed Unity 4.6.5 to the exe of the MonoDevelop in the Unity 5 folder (via the preferences), synched the project and now it opens up in one window again.
My guess is, multiple MD installs conflict with some sort of functionality that asks for open windows… or such
