User may experience various issues when Intermec handheld scanners are redirected through RDP session.
Some of the scanned data looks like a windows key combinations which cause various popups during scanning.
Please configure the client software (AppPortal/Web-IT/etc) with the Windows Key combination options set to Local Machine Only.
The issue has nothing to do with vWorkspace. Intermec handheld scanners are COM-port devices with the keyboard plug.
