Safe mode it closes fine just like 2,5.7.0 does why does this not work on 2,5,8,0 rrrrrrr!!
I uninstalled imgburn and reinstalled from your mirror 7 without all the extra programs opened it up with ez picker option on and closed it by clicking the red x top righthand corner. It says saving setttings, never changed any settings with in your program and it took 57 secs to close i think it has something to do with not installing those other programs maybye i do not know but i hope you can find out what the problem is (windows xp 32 bit)
there is another person that posted they have a windows 7 64 bit with the same problem too ,sounds like the same problem.
