When scrolling in the Windows explorer left pane, the drive mappings and/or folders are displayed double or overlap other mappings or folders. Hovering the mouse over these folders or mapping will correct this view.
This issue only happens when the "Favorites" and "Libraries" are removed from the explorer by a registry change on HKLM level. This also occurs in a session without RES Workspace Manager, so this issue needs to be addressed on Microsoft Windows level.
Add "Favorites" and "Libraries" back in to the correct registry path in HKEY_LOCAL_MACHINE.
