Hello, I've been trying to figure out why my TB program has stopped responding to the email button on my Logitech K270 keyboard. It calls up the Windows Mail 8, but not TB. Everything else on the keyboard works fine, but it will not call up the TB program. I've tried various settings in SetPoint, 6.9, but it won't work. I've tried contacting Logitech, but so far, they've been no help, so I'm hoping somebody here, has run into the same thing, and figured it out. I mean, why would the button work for Windows Mail, but not TB?

Thanks in advance.
