Moshe,
One difference between Linux and Microsoft or Mac, is that Linux has several versions of the same product.

If you installed a beta version, then of course, you are part of the group testing that version or that update.

If you chose a stable version then it should work on your computer without crashing.

if it is crashing, I would think that there is a strong strong possibility that your computer has a memory fault problem. First run the memtest program if you are trying linux for the first time. It will test the memory and let you know if it passes, or if it needs replacing.

Microsoft does checking for a select group of testers. They know they are testing a new feature. Microsoft also has a testing laboratory, or a group of testers at various manufacturers.

So before complaining about freezing, check your computer hardware. Report to us your success. By the way, Microsoft XP will not test that the hardware is ok.
