I noticed MacOSX SDL sets up working directory to parent of executable. On BeOS is should setup it the same way, but it only does when Tracker wasn't restarted. I checked code and it looks like a hack to me :( It looks for env variable and than comapres it to default when OpenTracker was started after boot, and wasn't restarted. That's probably ok, for that exact case. Unfortunetly that variable isn't always like that. For example, after Tracker crashes and is restarted, env variable most probably is different (depends on how Tracker was restarted, by what application, etc... for example: i have launcher application from which i can restart Tracker, and after that nev variable points to that application's directory, not Tracker's).
