Sage Exchange/SysTray

We are running a citrix environment and available resources are critical. Therefor we aren't a big fan of applications loading/running in the system tray. Sage Exchange requires connectivity software to process credit cards and appears to load every time the user logs in. Wouldn't be so bad if it only loaded when they needed it.

Anyone know how to disable the systray icon? I know we use /s for MAS500....
