I have a clip which contains a lot of hand-held shake. I followed the instructions in Steve's book on PRE12. I found the Stabilizer effect and dragged it over the clip. As soon as I did that my mouse became un-operative over PRE12; whenever the pointer was over the part of the monitor screen covered by PRE12 it became a circle with a diagonal line through it. However, when over a part of the screen not covered by PRE12 it worked normally and well. Also, as soon as I finished the drag and drop none of the keyboard shortcuts worked and I had to go to the Task Manager to shut PRE12 down.
Can you help, please? Many thanks.
