Quote I am constantly getting temporary freezes with the message that the program is not responding. A simple scroll in one of the folders can cause it, or just a click in the work area. This happened on my previous computer, and I just upgraded my entire system, but still have the same problem. Believe me when I say I have plenty of RAM and a very good graphics card.

Your signature's system specs are nice, but it would help much more to have you run the DxDiag test as described in the Read Me Before Posting sticky thread. It's possible that there's a driver or configuration issue with your system.

It would also help to know the details of your source clips. MediaInfo is a free and valuable tool, or you could upload a short sample clip to OneDrive, Google Drive, etc. and paste the link to it here so other members can examine it and see if it might play a role.

The DxDiag shows no problems. All the media is from my Canon, except for a few JPEGs from the Internet and transitions/PiPs from DZ. It would take forever to go through each on MediaInfo. Win 10 Home 64-bit
