Create a standalone with socket communications and send commands to it to show, hide and anything else you need the stack to do. The real trick is to build it so that it doesn't show up in the taskbar, else people will close it. When your app opens, launch the executable with the stack hidden. Then pass calls via socket to your stack as I mentioned. I did this once and it worked quite well, except that I didn't know then how to prevent an app from appearing in the task bar or the MacOS Dock.

The forum and dictionary proved "set the icon to (some ID)" doesn't work on Windows[1], but I could use the still-undocumented "set the statusIcon to (some ID)" property[2] to change the system tray icon.

My problem with this is that after the first time that alert is acknowledged, via statusIconDoubleClick in this case, any subsequent statusIcon changes are only displayed in the "Show hidden icons" of the system tray which in essence buries it from the users view (until the stack is relaunched). I confirmed this behavior with the Sons of Thunder product STSTray[4] which seems to suffer from the same problem.

The closest I could find is to use "do as VBScript" with an AppActivate command[5], but was hoping for something using LC script directly (although this forced me to learn some VBScript and use the "do as alternateLanguage" command[6] which were both foreign to me).
