I am getting a beach balling in an application I am working on, I
would of investigated more but I have noticed that some other apps on
my computer seem to be doing the same thing.
If I move my applications window it free up the block allowing an
event to be processed), but the instantly freezes on the next event,
this is why I think other applications have the same problem because
they exhibit the same behaviour, this includes the Applications Safari
when playing a movie, Quick Time Player but the sound keeps playing
and a Third party app called Opacity. s this a known issues.
It doesn't affect my MacBook Pro only my iMac and the issue occurred
in 10.5 and 10.6, I am using an NSOperationQue which may have
something to do with it.
One thing that is different between my MacBook Pro and iMac is that my
iMac is nearly always doing something in the background, without may
app running there is about 15% to 20% cpu usage and about 500 thread,
another difference between my iMac and my MacBook Pro is that my iMac
has only 37% of 1TB hard disk space, I have heard there can be some
issues with disk fragmentation at 30% or less hard disk space.
