groups and tags frame disappears

In OS X 10.6 and below, the Groups and Tags window remained visible even when I switched to another app, like Finder. Having just upgraded to 10.7, I am unable to keep the window visible when I switch, even with Devonthink still running. I’m probably overlooking a simple setting somewhere. Would appreciate suggestions.

I was right. It was a simple setting. Problem solved. Thanks anyway.

Glad to help. ;^)
