I had the same trouble working on a newly acquired old lathe some years ago. Raised the bench it came on by four inches: problem vanished instantly. Rule of thumb: set height so the cross slide feed handle is at your bent elbow height.
All my workbenches are likewise a bit higher than standard at 40 inches for the same reason. I'm 6'1" tall so you might want to tailor to your own height. The Myford bench is now 40 inches high and the ML7 sits on 2" riser blocks on top of that. Nice.
I also have a bar stool in the workshop that I sit on if working on small fiddly stuff for long periods.
