Sublime Text 2: Is it possible to clear or clean the project-switching dialog cache

I use ctrl⌘P to switch projects frequently. Until recently, I stored all of my .sublime-project and .sublime-workspace files in my home directory. In a recent cleanup I decided to move them all into a sub-folder of my home directory.

Now, the switch-project dialog shows the cached references to the old location of the project files alongside their new locations. It's a real pain in the rear because I have to compare the paths to make sure I select the correct entry.

Is there any way, short of nuking my install and starting fresh, to clear this cache?
