Problems with current v.2.0.1144 - Can I revert back to 2.0.1082?

[inaid]

I found my imac system is completly unisable with this version. Freezes every time I try to rotate. Inclusive some pieces made before can't press pull. If you uncheck anti-aliasing under visual effects the rotation works fine but the "look" is much worse than earlier version 😞

Is there any way to installe the 2.0.1082 version?

Thanks.

FWIW, I just tried completely shutting down- my system hadn't been rebooted for quite a while, and I had used some other graphic intensive programs- and after rebooting the file works fine with anti-aliasing on. So it might be just on the ragged edge of graphics processing capability.
