Hey, with help of the awesome community as a beginner i'm able to get rid of all the issues that i face during my first project in livecode.
But now i'm stuck in a very strange issue. I'm trying to put a status icon for my app and iconify the it. everything works great. But there are two issue that i'm facing when iconify the stack.

No1. I see a little box with the stack still showing and float over the screen when i iconify the statck and the stack get hidden to the system tray.
Check the attachment to see the screenshot.

No2. When i put the stack decorations to empty, the shadow is completely gone with it.
