Weird issue with HP Elitebook 820 G3 Touchpad. When I click the right mouse button on the Win 10 start button I get panel with shortcuts to System etc. However when I try to move the mouse over the panel it vanishes. This happens only with the lower RMB and not with the upper one. Also all Synaptic drivers from the HP website have this issue. When I use generic Win 10 touchpad drivers the issue is gone... Running Win 10 Pro x64 1903 with latest updates and fresh install. Any help with the drivers?
