Why can't I show timestamp on a shared variable?

I have two shared variables in a block diagram. They are in two different lvlibs, but both hosted on the same RT target.
 
One of them allows me to show the Timestamp.
The other does not.
 
Why? Is this just a bug in LV 8.2?

OK, I figured out the answer...
 
Because on the second variable, I selected "Shared Variable" from the palette, then did "Select Variable..." to get the variable I wanted.
 
If I had dragged and dropped the variable from the project window, then it woud have allowed me to show the timestamp.
 
8.2 Bug.

This is a known bug in LabVIEW 8.20 (CAR #40CHDO8O).  If you use the "Select Variable..." shortcut menu item on a Shared Variable node, the node does not get properly updated with the information about whether or not a timestamp is allowed.  The workaround, as you have discovered, is to drag the Shared Variable from the project.

What is the best way to find out about known bugs before I post about them?
