What is going on Apple?

I have just experienced two of the most frustrating weeks since upgrading to Mountain Lion and then upgrading to the latest versions of FCPX and Motion. I've experienced constant crashing in both programs especially in the process of trying to modify a preset title by opening a copy in motion. If I tryed to insert the updated version in the timeline within seconds the program would freeze. I would change items in the copy and find the changes not updating in FCPX.

At one stage, while using FCPX the clips in the event browser stopped playing. As well as that Motion would crash not long after expanding the Gui out to my second monitor. From that point on I was unable to use the second monitor and had to delete the layouts folder because I couldn't see the Timeline anywhere. This fix worked for a while and then boom, crash, back to the same sitiuation. Unbelievable.

I have to say, I've nearly totally lost my faith in both these pieces of software which is a pity because FCPX does some amazing things. So, what fixed the constant malfunctioning?

I downloaded a copy of Mountain Lion and did a clean install, then loaded FCPX 10.0.6 and Motion back on. Seems to be working fine now. No crashing, anyway, from both programs.

I don't know much about software but there seems to be something very wrong with the whole updating process if I can solve most of my issues with this drastic action. My question is: Why on earth is this necessary in the first place. It all seems totally unprofessional.
