The tray icon does not appear for version of Spark 2.5.4 and above when the user is loged in as a limited user (non-administrator). 2.5.3 is the latestes that works, I just tried 2.5.6 with the same results. If it is set to start in the tray, it simply disappears (task manager shows it running, but cannot be accessed). For security reasons, I cannot have my users running with admin rights. This happens on any XP system I have tried. If the user is placed in the administrators group, it works fine. Is this a known issue? I’ve seen discussion threads on similar issues but none seem to be covering this exact issue.
