Hello!

I am trying to implement a popup control in the Cocoa view. The view coordinates are flipped (function IsFlipped returns YES, the (0,0) coordinates are at the TopLeft corner).

Here is the peace of code:

NSRect frame = NSMakeRect(x_coordinate, y_coordinate, 32.0f, 32.0f);
NSPopUpButtonCell *popUpButtonCell = [[NSPopUpButtonCell alloc] initTextCell:@"Dummy" pullsDown:pullsDown];
[popUpButtonCell performClickWithFrame:frame inView:view];

For some reason, the popup is appearing constant 20px below the provided coordinates!

Did someone encountered similar problem?

Thanks!
