NSPopover bug?

In the Overview example, the NSPopover when it appears 'tears off' the first time. Click on the popup button then on the view that pops up click on it just below the button and drag to the right, the popover becomes a form with buttons, but the view isn't displayed - just the top of the view is displayed multiple times. This only happens the first time you click on the Popup button after that I can't get it to do this. Anyone else see this happen?

Delphi XE6 on Windows 8.1, OSX 10.10, mCL 

We have investigated this here and have applied a fix for this issue. Please note that in the next version, the popup will no longer display a tear off window until the WindowView property is assigned.

Kind Regards, 

Thanks again Pieter
