I clicked on something accidentally and I lost my functionality.Please see screen capture of what my workspace looks like now (I can only upload one image with this post and can’t show what it used to look like before) I will have to do that in a second post. I have no scroll bar no tool bar and nothing to the right to edit my videos! Please help with specific steps to restore!!
