I love the new lion but 1 major thing I have noticed since the lion update is that I have to restart my computer way too often. Mission control becomes laggy and will just randomly quit working. I don't know what causes this but it requires a restart to fix the problem. Final cut pro X crashes alot. Motion crashes more often than fcp, and the overall performance of my computer can also be sluggish at times. The sluggish part does not last long but it does happen. This was never a problem before lion. In the past the only time I restarted my computer was during software updates. I am using an iMac 24" model 9,1. My 13" mbp has been great with no problems. Although the mbp may have issues I just don't use it enough to find them. They need to patch this stuff quickly. Is this just a imac problem or does it happen on all systems.
