I've thought about remembering dialog values, but I guess so far I've been
too lazy to do it or, to put a better construction on it, too distracted by
other things. It shouldn't be hard to do -- just a matter of maintaining a
data base of previous entries that are flushed when the active data set
changes. Actually, the linear-model and generalized-linear-model dialogs
already do this.
I'd be interested in the other little niggles as well.

I certainly don't want to press this issue, since I'm grateful for what
you've already done (and it's surprising how much mileage one can get from
the basic widget set). I see this as primarily a Windows problem because
users of other computing platforms (possibly with the exception of some Mac
users) tend to be more sophisticated about installing software.
