Hello, I do have an issue since I updated from VideoPad 7 to 8. Till version 7, I could just drag and drop clips within the same sequence to swap their position. When I did move a clip, it would place itself automatically between the two clips, the space is automatically made and the previous/next clip were not overwritten or cut. But now, each time I move a clip on the sequence to change its position and place it between two clips, it just sits on top of the previous one, overwriting it. What I need to do is just insert a clip between two other clips without overwriting them. This previously could be done simply by dragging the clip among the two other clips. Now, I am forced to move clips on other empty sequence tracks and rearrange them manually, which is uncomfortable and time wasting. Does anybody has the same issue? How can I move a clip between two other clips, without overwriting them, but creating space automatically for the insertion? Thank you in advance.
