Opera 9.5 has never run stable for me on a Mogul - it simply requires tons of RAM. If you want to run that properly, you'll need something like a Diamond or Touch Pro. To give you some perspective, the Diamond and Touch Pro have 288MB RAM while the Mogul has 64MB.

In any case, you can try using the latest nueRom (if you're a donator) as that adds quite a bit of memory to the Mogul. Ultimately though, you should try to do whatever you can to get your phone swapped out to a Diamond or Touch Pro (once it comes out).
