I have a button on the lower left corner of my new theme, and it opens a popup menu that resembles the windows start menu. I have it so it pops up in a specific spot towards the bottom so it spears to 'dock' into my taskbar. But to have room for the start button, i need this popup menu to be 10 pixxels from the left of the screen.

So my question is this; Doesn anyone know how I can make a bitmap apear only when that specific popup menu is open?

where !mylabelshow would make the bitmap appear. You'd have to use hotspots or so to hide it again.
