Has anyone seen this error before?

It says CLFNM0257E: An error occurred trying to get a previewer from COR. Please contact your administrator. Widget is disposed
Then after I click ok my preview pane no longer works. However closing the tab and re-opening it fixes the issue. I am running 64 bit vista...
Weird right?
Update: this error seems to only happen with I use my scroll wheel on my mouse... It opens an email at random when I'm scrolling and that error shows up. When I close the email the preview pane doesn't work.
