I just installed version 3.4 today.  Everything seems to run normally, but for some reason, once I start a clip by hitting "Enter" on the keyboard, the ScreenMonkey window deselects, and I can't use the arrow keys to navigate through the clips or hit "Enter" to start the next clip.  The only way to get the keyboard to recognize again is either by clicking in the ScreenMonkey window or by using the keyboard shortcut to clear the layer.

In past versions, I could hit "Enter" to start a clip, and then if I decided to start a different clip, I could just hit "Enter" again to start the next clip in the list.  Now, I have to re-select the ScreenMonkey window before it will let me do this.
