Interfaces only support methods.  I don't think that interfaces that  
support properties make sense.

Hi, all...

    I've been having trouble with an unhandled NilObjectException
for quite a while. It appears to be in the IDE. I've reported it through
FogBugz; it's case 5271, i.e.,

<https://realsoftware.fogbugz.com/default.asp?5271_muob2sdp>

    The details are that I open a project and then close it. Then I
open a second project. That's when I'm alerted about the unhandled
NilObjectException.
