What VP version is being used? Have you inadvertently locked the tracks that you want to move? (Right-click at the left of the track.)
Can't drag clips? What about right-clicking one in the bin (top-left) and choosing a placement, such as Overlay at Cursor?
Share a little project that is doing this and others will experiment with it. It's easy, and can be private via a Personal Message. Click the envelope at the top-right of this window.
Follow these steps...
Back up --- With your project on the timeline, click on MENU at the top-left. Click FILE|BACK UP PROJECT FILES TO FOLDER. Choose a folder and SELECT FOLDER.
Upload --- Use a free server - Google Drive, MS OneDrive, etc.* - to upload the saved, numbered FOLDER. Do NOT upload the individual VPJ or export file.
Get link --- Get a public link. If using Google Drive click GET SHAREABLE LINK. If necessary change "restricted" to "anyone with the link can view"
Share --- Click COPY LINK | DONE. Paste that link here, or click the folder at the top-right of this forum to message it privately to me. It won't be shared.
* Before uploading, right-click the folder, click PROPERTIES. Look at the File Size to confirm that it's not too big for the free space on the server.
