MonoDevelop: Autocomplete in Editor scripts can't see regular scripts?

After upgrading to Unity 4, Autocomplete no longer works between Editor and runtime scripts. It doesn’t fill in the class names; when I declare a variable, it doesn’t see any of the members.

Anyone else experienced this? Is there a solution, or am I going to have to wait for a patch? (I hadn’t realized how dependent my workflow had become on autocomplete…)

All of the runtime scripts see each other just fine, and the builtin classes and other Editor classes are seen just fine.

Solved this problem by quitting Unity and MonoDevelop and trashing the MonoDevelop “project files” (the ones Unity generates). In case anyone else runs into the same issue.
