I am running RGS 7.6 on a Windows 10 Platform using RGS to Login to a Linux Workstation Pool running Redhat 7.4.
When I use the Shift Down, Space Down, Space Up N key to minimizes a Linux/ RGS window. the window is minimized as in past releases. The problem is when reactivating ( maximizing) window again all of the functions in the maximized window are greyed out until you press SPACE DOWN, SPACE DOWN.
To test the problem I down graded to the previous version (7.2.2) and did not encounter the issue. I can minimize using
Shift Down, Space Down, Space Up N key then maximize using the mouse and the window is completely functional.
