Alban - Can you provide the URL? I'll definitely try it out, but can find it either.

If you're using an HP laptop, try disabling/restarting the HP Support Solutions Framework Service. It seems to have worked for me.

It seems my original post (I'm Bob) may have been lost in the ether or perhaps wasn't approved by the moderators. Here is the link with the post I wrote about the behavior and the workaround -> http://plugable.com/2016/01/19/flash...-7-9-m4-driver

Can you see Bob's posts now?
I think the short post + URL might have triggered a moderation hold.

Solved with Bob's post workaround.
Thank you.

Will this be fixed in a new driver release?
 

I see the registry hack posted in http://plugable.com/2016/01/19/flash...-7-9-m4-driver . I have not tried this yet. I would rather wait for updated driver. I reverted back to 7.9 M2 version.

I am particularly interested in M3 because this COO's computer has experienced the "Microsoft Office protected view is crashing when using hardware graphics acceleration" issue which should be fixed in M3.

screens flickering W10 Dynadock fixed
 

I have a Toshiba Portege z20t upgraded to Windows 10 and connected to Toshiba Dynadock 4k. I also had the two screen flickering/switching problem that made them unusable and this seems to have stopped the z20t from recognising its keyboard dock. However, applying Bob's fix at http://plugable.com/2016/01/19/flash...-7-9-m4-driver has enabled me to get Dynadock 4k unit working again via micro-USB socket on z20t tablet.

I still do not know how to get tablet to recognise its keyboard dock again
