Let’s set the stage:

You are in your Blackboard grade center in your course.

There are plenty of columns, in fact you are pretty sure there are more than you can see at the moment.  But … there is the vertical scroll bar… and there, I’m pretty sure, is where  the horizontal scroll bar should be, but it is not.

Did I mention that you are on a Mac?  (I am too, no shame there.)

OK – this is a system setting on your Mac.  Go to the Apple menu.

Select “System Preferences…”

Now select General.

and finally, make sure “Show scroll bars:” is set to Always.
