Correct. However there is the X button in the bottom right corner that should close out of the window (or minimize). Once I go into the menu, I'm stuck in the messaging app and cannot bring up anything else until I do a soft reset.

This has specifically happened when viewing a text in the default messaging app. If I click to view the message it will open up. As soon as I go to close out, the lockup occur. I can view the message with no problem. The window will only close after a reset.
