We have a selection of 8 assorted Dell laptops - Latitude 5490 and 3390, XPS 13 2-in-1 - all less than 12 months old.
We also have a couple of different docking stations in use, Dell D6000's and one Dell WD15 also less than a year old, connected to extra 23" monitors to be used as a "wide" desktop when connected to the laptops.
We publish some applications through RDWeb from a Windows RDS server - both of these servers are Windows 2016.
What happens is the application runs happily, but if we plug a laptop into a docking station while the app is running (or unplug from the docking station) the application locks up and doesn't respond to key presses. We can close it from the user's laptop taskbar or by clicking the "X" but other key presses are ignored. We can also move the Windows by dragging the title bars.
Reversing the attach/detach of the docking station does not resolve the problem.
The problem affects any application that we launch through RDWeb, including "standard" Windows apps like File Explorer.
Any ideas how we can fix this?
Thanks
