I am running Muvee Reveal on a HP Pavillion Laptop with Windows Vista... love your product but i find that it runs veryy slowly and crashes frequently making it rather frustrating and means unless i save after every step i end up losing my work. Extremely frustrating and making muvee making a looong process and analyzing and buffering seems to take forever and also loading the clip for magic moments. Is this is a frequent problem or am i the only unfortunate one? if you have any tips or proceedures to help solve this please let me know as I am getting very frustrated by it!
