Transaction register question

[Robert Kesterson]

I've got the latest beta version of gnucash installed on my Mac, and it 
has an annoying new feature that I can't figure out how to turn off.  I 
think it has already been mentioned on this list recently, and I tried 
to search the archive at lists.gnucash.org, but that web page is 
horribly broken in Safari.

So anyway, the question is:  How do I turn off that second scrollbar on 
the left and return the register to the "old" behavior?  I know it must 
be possible because my checking account register operates just like it 
always has, but my other accounts (credit cards, etc) have that second 
scrollbar and they don't respond to the "Enter" key like they should (I 
have to use the arrow key to move off a transaction, then click the 
button to record the changes).

I know I could roll back a version or two, but if there's an option to 
turn that new feature off, I'd rather just do that, and I thought I 
recalled someone saying you could do that.
