Arrow hovering "+" & "-" feature gone suddenly

I opened up Cubase 7.5 recently and all my preferences, custom key commands and recent songs (list upon opening) had gone away. It’s like I reinstalled the software. It was annoying, but most of it I could redo pretty quickly. But one thing I haven’t been able to figure out is this: I often use the function where I hover the mouse arrow over a numeric value (like the location numbers in the transport panel) and if you move it slightly up, a plus sign appears, and down for a minus sign. It doesn’t do this anymore. Anybody know why? I’ve looked around a lot and can’t figure it out.
