Thanks Panos! I didn’t see an announcement about callbacks… So is that different duration in Windows a predictable proportional amount compared to the duration in OSX? Is this proportion always the same number? (Or will I have to find this out myself?)
My application is cross-platform with many sets of callbacks. If I can simply multiply a callback value by a constant to get a new value for Windows, that would be fine with me. I’m hoping the durations of files in Windows is really not “random”!
