Unable to use arrows in viewport

[steel]

I am new to Realflow and may just be missing something obvious. When creating an emitter, or an object, then switching to Move or Rotate brings up red, blue and green arrows. This is standard stuff I'm use to in Cinema4D but my problem is I am unable to click on them.

All I can do is click and drag to create a selection box within the viewport. I cannot actually click on any of the arrows to move my emitters or objects around. In fact clicking inside the viewport seems to do nothing as I can't even select an object by clicking on it. Shortcuts to move around the viewport by holding alt work and I can right-click inside the viewport to bring up options so I'm not totally locked out. I just can't use the arrows as they don't even become highlight by moving my mouse over them.

I feel like I'm just missing some setting I need to switch.

Hmm, don't know what it is going on with your mouse. Sometimes I forget to activate the split viewport before clicking, but in your case it might be something with the type/driver of your input device....?

Is this in C4D?

If not, and you are in Windows or MAC, maybe I have an answer for you.
