I finally found the bug in iphysics yesterday! For some reason, the newton dll file got corrupt and by replacing the dll from the newton folder, i got it working perfectly! A bit relieved now, tho the error when quiting any app using iphysics is still there! Neways, i began work on one of my mystery projects today! Even tho i have my final xams in less then a month so progress will be very slow at the moment but hopefully it will be completed in some time!
