Hi, is it possible to put some args or something in a button script to make a menu appear when I right-click on the button?
Yes, that's called a context menu and you can configure many of them in many different ways. One that appears when you right click over certain file types, another different one that appears when you right click over an empty area in the lister, one that appears when you right click over the Opus system tray icon, and so on.
So in other words, you'd have to be more specific about exactly what you want to do before we can help you.
Oops sorry, I'd misread your question, forget what I said up above.
You can still do this though, you have to configure a 3 button button to do it.
Thanks, not quite what I wanted, but it works!
