I upgraded to parallels 3. I do not understand some things about it. I run it, but when I press the button for coherence, it does not seem to work at all. Nothing happens. What it is supposed to do? Why this do not function? I also run the parallels compressor. It took me about 5 hours in my mbp c2d and it did not complete! I suppose it needed about 5 more hours! It took forever. My mbp was almost on fire (fully working) so I cancel it. Another point: How do I run win applications through mac os x? I tried to run some .exes but they did not run. Please help!
