Hi, I'm a newbie user of across as of today. Have an iMac 27" and a Macbook Pro (MBP). I've used the Target Display Mode to connect my MBP to the iMac to use as external display. With my old hardware KVM switch this was working well, but want use the Mac keyboard and mouse to share between both. If I have iMac as Across Server and separate (not connect) MBP as client I can switch keyboard/mouse back and forward with the two option keys, no problem. When I have the Across Center open I can see connection moving from one to the other. As soon as I connect my MiniDisplayPort and use the Target Display Mode, the option keys are no longer responding. IMHO this seems like a bug, but I'd love to be wrong. Anyone has seen this before and knows a fix or workaround?
