Strange behavior.
 

I remember at one time in Vegas 8, when you dragged the edge of an event to trim the event, Vegas would preview the trim in the Preview window. I just realized today that When I drag the edge of the clip, Vegas is only previewing the trim within the video event, the preview window only shows the frame that the timeline play head is paused on... Is there any way to get it to the behave the other way? I don't know if it's a setting I changed that caused this...

EDit: Okay FIXED! I did a "Default All" under the General Tab... I must have clicked on an option in there that changed this behavior....
