1. Server key mappings
I thought it might be the Remote Desktop keyboard mappings, see https://msdn.microsoft.com/en-us/library/aa383500(v=vs.85).aspx, but Shift-PgUp/Dn are not listed, I also did a quick test and could go up and down unlogged directories over a Remote Desktop connection to a workstation.
mstsc.exe can have problems with the state of the shift key taking a while to get to the other end, are you pressing and holding shift down, and then pressing PgDn as needed?
Are you using a different remote access program, which might be using those keys?
Also are the keyboard layouts the same at both ends?

2. Behaviour of Shift-PgDn/Up
This might be a bug, given the below

Directory window
select c:\System Volume Information
Return, to log, which will fail with an "Access Denied!" status
go up a few directories
then Shift-PgDn will goto c:\System Volume Information

so I would expect it to also visit unlogged because of error directories.


3. ZTree window on error
Might be caused by the way that ZTree is reporting the error.
From memory on errors it tries to grab focus.
