When the Mathematica application loses focus, palette windows disappear (normal notebooks and dialogs (
CreateDialog) stay). This is usually convenient because the small palette windows would clutter the screen.
I would like to use a palette as a drag-and-drop target. For this I need to keep it visible even when another application is focused. Which notebook property needs to be changed to prevent one particular palette from disappearing when Mathematica loses focus?
(Why I want to keep this drop target as a palette: it's easy to open from the Palettes menu and it has a small frame.)
Note: Per the comments below, this does not seem to happen on all systems.
Update: It seems that this is an OS-wide behaviour for this window type, at least on OS X. The answers suggest changing the window type (
Here are two screenshots to demonstrate. The only difference is switching the focus to the browser.
