When you right click ESS Beta from taskbar, you see the pop up Display Alerts, Display Notifications on desktop, Display balloon tips in taskbar, you cant just click to close the pop up, and have to click Open Window than close from the ESS Beta main GUI. Edited to add suggestions: Think that the spelling should be consistent, example, Display Alerts, Display Notifications on Desktop, Display Balloon Tips in Taskbar, and that a close window option should be added to the bottom of that popup. Next if you create a firewall rule, with the Display Notifications on desktop checked the rule you created than displays in a small pop up above the ESS icon in taskbar and cant be closed until you uncheck the popup box under Display Notifications on desktop. All in all nice beta running very stable, this is on Vista Ultimate x 86. Regards, Wake Edited to add: The weird spelling I get on that pop up box is caused by zoom feature of a Microsoft Intellipoint keyboard, and the hide window option at the bottom of that pop up only comes up random.
