In calc cursor navigation jumps several cells when using the arrow keys - any known fix?

The behavior changed along about v5.0+ when using the arrow keys you could move from one cell to the next whether right, left, up or down. Now when you press enter it goes down a cell (found the setting to change that one) but if you use the arrow keys you jump hundreds of cells in that direction. Nothing I have found to change it back. I did see a post about the problem but no real solutions. Any ideas?

Problem is unknown to me. Make sure your Control key isn’t stuck, as Ctrl+Cursor jumps to the next data/non-data boundary.
