Some of these issues could be a software version issue, or a configuration issue. Can you please share some more detail about your environment, such as which software version you're running on the MX300, what type of Mac are you having issues with (there is a known Apple issue with MacBook Air when using a mini display port to VGA adaptor), what are the exact steps that you're coming across the issue with the PC that's requiring a reboot, and how do you have the presentation settings set on the MX300 (Auto / Manual / etc).
