Thanks for the note. I will try to check Device manager for yellow exclamation points when it happens again. Sometimes I can make 4 or 5 copies with out having to reboot computer, sometimes it is just one copy. Thank you, Danny

I am using using my Inspiron 1720 laptop and imgburn to burn a dvd to disk from a file on my second internal harddrive. The file I am burning is an .iso file. I boot up my computer, bring up imgburn, and successfully burn one DVD. After this first burn, there is no device detected any longer. I have to reboot my computer after each attempted burn. I have eject disk checked, and nothing else. here is the log: I 21:42:07 ImgBurn Version 2.5.0.0 started!
