Variable Contents Not Shown When Hovering

I know there was some discussion of this a couple of weeks ago. I saw an
additional symptom of the problem today and thought I'd throw it out for
discussion. I'm on WDSc Version: 6.0.1 Build id: 20050725_1800. In Debug (as
a result of a SEP) I hover my cursor over a data item in my calc specs and I
do not see the contents of the variable. If I highlight the data item (using
cursor drag - double click does not highlight), move off the data item, and
then hover back on, I can see the contents.

However, the new thing I encountered today is that I can hover, without
highlighting, on a data item in my D specs and it shows the contents of the
variable.

So, hovering in C specs does not work, hovering in D specs does work. Has
anyone else encountered this problem?

Also, am I current in WSDc? I did the updater thing and got an interim
update, but nothing that changed version numbers.
