Keyboard Issue

Hi All,

I just want to share something strange with the Grasshopper (I use 0.9.0076 version). Sometimes, which I can't predict when, I can't operate any keyboard shortcut, even delete button/space bar. My instance solution now just restart the program (Rhino+GH), which is annoying especially if I'm in the middle of process.

I just wonder, is there anyone who's facing similar problem? or maybe know why does it happpen and know how to resolve?

Thanks in advance

G
