I am truly beginning to hate the drivers for this already POS graphics card. Although my minimal test cases passes fine with the 10.5.6 update, both of the larger projects I was working on earlier this year still exhibit the bug. Even more annoying, now that I have take the time to upgrade these projects with the workaround I found before, the crash is still present. The crash logs are identical to before, so I am forced to assume that Apple only found and fixed one facet of a larger problem.
This has left two of my projects hanging since mid-September, which is an nigh-unacceptable state of affairs. At this point of frustration, if I had the cash, I would go out and replace this only 4 month-old machine with one of the newer, NVidia based models, but alas, my pockets are not that deep 😦
