MonoDevelop error when type open bracket

I get this error every time I type open bracket ( ( ) in Js. This error didn’t appear if I using C#.
I have try to reinstall Unity and fresh install Unity. I use version 4.6.1f

Somebody could help me giving suggestion to fix this error?

Go in tools - options - text editor - general… now deactivate the Enable Parameter Insight… or you can install the net framework… http://www.microsoft.com/en-us/download/details.aspx?id=30653
