Arrow Keys pushing objects the z-depth field

Hello!
I’m using Toon Boom Harmony, version 10.3.0.

So normally in my camera view the arrow keys will push an object only in the x and y axis. The only time I move an object through the z-depth field is when I have my “Top” window open. BUT
lately it’s been pushing objects in the z-depth/axis even when the “Top” window isn’t open.

I’ve tried rebooting the program, and rebooting the computer, which have all proven to be temporary fixes.
Even if I haven’t opened the “Top” window at all since the program’s been open, this problem still pops up.

Can anyone help? :frowning:

PROBLEM SOLVED -
Apparently replacing the existing camera with a brand new camera from the module library fixed the problem! In case anyone encounters this in the future! :smiley:
