This bug has been around for a while, although Logos can't seem to reproduce it - https://community.logos.com/forums/t/173965.aspx
But it's still happening and it is so annoying.
At some point in the process of using the Sermon Editor, moving the cursor over the centre scroll bar causes the sermon document to leap all over the place.
Here is video evidence!! 2806.Recording #5.mp4
I have no idea what causes it. It doesn't always happen; it seems to suddenly start happening after working in the sermon editor for some time.
If there is any way to fix it, this pastor would be very grateful!
