since using v12 I have alot of slowdowns where as with 11 it worked nicely (considering :-), is it due to security fixes maybe?
G5 2.3 GHz OSX 10.58.

the beachball will come up and spin for a bit sometimes 30 secs sometimes longer then resume,
I have 3 days worth of this same error grab from console:

I'm guessing this is every spin of the beachball

    I can't help noticing there's been an unusual amount of people reporting problems on G5 recently. This may be coincidence, but: What happens when you install the G3 version on your G5? Do you still see these problems?

    oh good it's not just me. :-)

    I will try it out.

    this last version(s) seem to be better or much less spinners.

    For the record, though, I'll point out I build and develop on a G5.

    The CGAffineTransformationInvert line is a harmless OS glitch. It occurs when the animated arrow appears after a completed download due to the coordinate system used.

    hmmm, it seems the G3 version does work better I will do a comparison tomorrow.
    I do recall thinking the v11 at times I forgot I was on an old machine.
    so it was definitely noticeable.
