I don't know if something has changed in my settings, but now when I double click to select a video and audio event on the timeline to cut and paste it into another section on the timeline, only the audio OR video pastes, even though both were cut. Have done this successfully, same way many times, so don't know what is going on. The online help and other sources I've consulted are of no help, so hoping someone out there has a (probably very simple) answer. thanks a lot.
I got my other problem about combing files solved, thanks to all who replied.
