Have had one problem only here, with the final release. The crash when changing sunlight setting several times - like if i set the shadow intensity level 4-5 times in a row. No other crashes, no low resources, never a memory warning (have 2GB) on a P4 Intel motherboard. Have spent many hours working on scenes with never a problem.

And i'm using all the high-speed OGL (OpenGL) render and GUI settings, fast redraw and such.

Imported a few Poser figures (made in Poser 6), but not staying connected to Poser - and manipulated them easily, no problems there.

I had been getting a few OGL related crashes with my Intel onboard graphics chipset on all the pre-release builds - so i finally got around to buying a GeForce 7950 display card and all crashes (except that one mentioned above) immediately stopped.  

I'm happy and productive with the final release.
