On Citrix under Windows 2012 R2
there is a situation where some level two menus are not completely visible and
have arrows to scroll up and down to view non-visible items.
In the case where there is only one menu item, the item disappears entirely.
This error does not affect other Windows versions.
The error is related to Windows 2012 R2 and possibly with multiple monitors attached that have different resolutions.
Microsoft has released a Security update to address other security issues but also address the menu scrolling issue.
