Grasshopper/Rhino typing BUG

Hello, I am experiencing what seems to be a bug.

I am running GH 0.8.0051.

I will be using GH fine and then all of a sudden (I haven't been able to figure out what I am specifically doing at these specific times) anything I type into grasshopper, even using things like Delete and CTRL+C and things like that will always type into Rhino and Grasshopper does not register it.

The only way I can stop this from happening is to close both grasshopper and rhino.

Seems like a bug?
