I have a macbook pro 4,1 running OS X 10.5.8. Whenever I try to run Fluenz (language learning software) it attempts to load then crashes. However, the program runs fine whenever I run the computer in "safe mode." I think this means there is likely another program on my computer conflicting with Fluenz. Is there any easy way to find which program is causing it to crash? The program runs perfect on my roommate's macbook pro which is the same model as mine. I have tried logging in as a guest and running the program and it still crashes. I am out of ideas
