I have run Instruments and I see a ton of these calls:
-[NSWindow fieldEditor:forObject:]
So I indeed see that there's something I am not doing right with the
NSTextField.

Use Instruments to find out where the slowness lies. Come back once
you'e got more information and still don't know the cause.

Hi all!
I have a Cocoa view that reacts to -mouseDown and -mouseDragged
events and then draws something via -drawRect method.
It has about 50 objects that are either NSBezierCurve or
NSTextField. The problem is, after a few seconds of mouse dragging,
the view becomes very sluggish. I release all of the NSTextField
and NSString objects immediately after drawing them.
What could be causing this slow-down? I'd appreciate any advise.
Thanks and best wishes,
Artemiy.
