OverDrive Media Console Doesn't Wake Up

Using OverDrive Media Console version 2.6.5 on my PlayBook with OS 2.1.0.1753
With OverDrive open in a book, put the PlayBook into Stand By via the battery icon. When I next wake up the PlayBook, OverDrive is still open at the last page but doesn't respond to any page commands. I have to shut the app and restart it.

Is this a known issue?

I will take a look tonight and see if I can recreate that on my PlayBook. :)
