Personal Property Entry Box doesn't work

The entry box for personal property taxes does not register numbers when typed.  This is under "Deductions and Other Credits" "Cars and Other Things You Own".  For the record, I'm using the CD version.  I've closed the program and reopened it - this does not make a difference. 

 

Several other people have also registered this problem under the "Personal Property Tax" question already answered, but it doesn't seem like anybody has seen these posts.
