code loss when cancelling during save.

I just got bitten by a code loss.  I'm not sure what to search for on Fogbugz, so I'll just ask if anyone has already logged it.

1. Start with an existing method

2. Add a line assigning to an unknown variable. e.g. blah := 0.

3. Click on another method

==> "Contents have been modified, what do you want to do?"  

Good!

4. Hit cancel, then Save method.

     When asked "Unknown variable: blah please correct"

     click <cancel>.

==> code pane shows it is still dirty.

5. Click on another method.

==> code lost.

Bad!

(P.S. you don't really need to do step 3.)
