When I 2xClick on a MIDI clip... anywhere... I get the PRV at the current time. NICE!
 
The only times I get the PRV at the -0- time mark is when I open it from the FIle Menu or Alt + 3 shortcut, which you have to do when several tracks are selected. NOT NICE!
 
Unless there's another way to open several tracks in PRV at the current time, I think there is a bug because X1 doesn't do this.
