Firstly, thank you everyone for the information that is being shared on here – we have been following along and using this information to guide our own testing. Our summary is that there is an inherent issue in Windows that causes the black screen, and we continue to investigate whether our software is somehow exasperating that issue.
In order to help us investigate, we would welcome the opportunity to examine a machine in this black screen state – our own internal testing has shown a few examples of black screens, but not in the manner described in this thread. If anyone is able to recreate the issue, or is able to leave a machine in this state whilst we establish a remote session and investigate then we would be very grateful. Please ring our support number and we’ll jump straight onto your system – we have developers on standby to investigate!
Darren.
