Sounds to me more like you just inherited the problem from your 10.3.3 installation, rather than redeveloping it. An easy way to test whether it is a user preference related problem is to create a new user, log in, and see if the applications work there. If they do, there's something in your user Library folder that is corrupt. If they don't, then it's more system-level. Another thing to consider is that problems like this can often stem from bad RAM. If you added RAM to your computer, especially if you went looking for whatever is cheapest, consider removing it and replacing it with high-quality RAM. I'd recommend Crucial the most; they're owned by Micron, who is a very good memory manufacturer. As long as they use Micron chips on their products (they sometimes use other manufacturers when supplies are tight), they're excellent quality. Samsung easily makes the best memory, but doesn't sell it to the public. Some companies will sell you Samsung chips for a premium, however I learned through experience that even the PCB that the chips are mounted on can cause your memory to fail, so I'm waiting to hear a lot of good information about some vendor that definitely has good PCBs too. Places to avoid: anything that you're buying because it's the lowest cost, and especially 1-800-4-Memory, aka Coast-to-Coast. Hands down, the WORST quality memory you can buy.
