Adobe
If this were the only problem Adobe products had with Lion, and if we could believe Adobe after all the BS they put out there, there might be reason to give them the benefit of the doubt. Look at the tech note they have posted, the list is long and interesting. And, it doesn't include everything, users have posted many more problems. Apparently, Adobe only became aware of Lion yesterday....
This is a joke, get your act together, Adobe. In some ways its too bad iOS became so dominant, so fast. Before that, MS, Firefox, Opera, etc were all after Flash (even though Apple got all the press for it, do a search if there's anyone thinks I'm making this up). Flash just might be gone on the web now if some companies hadn't reversed course to give them something to take on Apple with. Someone needs to pry Freehand loose from Adobe's fingers, and make good competitors to all the rest of that crap, so this company can be put in the ground where it deserves to be. I'm sure their good people will have no trouble getting better jobs.
