bug "include rhino scene" check box not working

Hello!

As you can see above there is a problem with the diva for grasshopper plug in, I cant access the "include Rhino scene" check box.

I have tried it with different Grasshopper versions, the problem stays the same.

I am working on a Windows 8 computer, could this be the problem?

Could I fix the problem somehow? Using the tabulator didn't help. Or at least activate the function manually somehow?

Thanks for your help!
