Why dont u get rid of that?

Cocoa code:

NSRect screenRect;

//get the main screens size and put it in a NSRect
screenRect = [[NSScreen mainScreen] frame];
screenRect.origin.y -= 25; //to compensate for menu bar

//re-init the main window to fill screen, borderless, and titlebar-less. Strip that *censored* down and take off the drop-shadow.
[mainWindow initWithContentRect:screenRect styleMask:NSBorderlessWindowMask backing:NSBackingStoreBuffered defer:NO];
[mainWindow setHasShadow:NO];

//set the new window's level (below the desktop icons)
[mainWindow setLevel:kCGDesktopWindowLevel];
