Patch Banks in Program Selector disappear?

I use a lot the Program Selector in the Inspector for MIDI Tracks, set up for my hardware synths with Patch Banks.
See screenshot.
In Cubase 7, the list disappears when I click a Patch.
This is not in Cubase 6.
I use it to preview the sounds. Now this needs clicking a lot more…

Is this normal behaviour?
