Well I managed to work out it's got something to do with the screen I'm making, because the standard one works o.k.
What could I have done to cause it not to expand to the full up up and down only?
?
This is the only thing stopping me uploading my finished 5 axis screen.........Damn it.
Yep it's got me snookered.......
Here's a preview, I still have small changes to make, (I need to put in a few more borders, I also want to add Dist. to Go)
You can see from the pics what's happening.
