Double Click M File Opens New Matlab Session

I'm running R2010a on Win7 x64. When I double click a .m file in windows explorer, it proceeds to open a whole new matlab session, even if I'm already running matlab with an open editor window. If I right click the file and choose "Open With: Matlab", it opens the file in the existing Matlab session.

Has anyone else experienced this problem? I'm not sure if it's a matlab problem or a windows-talking-to matlab problem . . .

After following these links, the problem is still unchanged. Two intances of Matlab are opened when I click two different .m files from a folder in window explorer.
