'Sync MonoDevelop Project' button does not launch Monodevelop.

I was using the button OK in MacOS.
After I install textmate, the ‘sync monodevelop project’ button just shows .sln file’s content with textmate.
How can I fix it to launch MonoDevelop?

Thanks in advance.

You probably need to go under preferences and change the default editor to MonoDevelop. When you installed textmate it may have bumped your setting.

Oh~ It works!
But I cannot associate textmate to edit scripts. ;;
