Hi, New to the forum but have been using VideoPad for a while now. I'm having an issue whereby, whenever I press the shift key, the software scrolls around the timeline seemingly randomly. This happens when I try to select multiple clips and even when I'm typing text into the dialogue box when adding text to the project. Really strange - has anyone else had a similar issue? Can it be solved? It's really causing issues and makes the software unusable. Many thanks.
