With version 1.50 I made the usbit32.dll multi-threaded, making it is possible to backup or restore multiple flash drives at the same time. Because I rewrote some major parts of the GUI app and the usbit32.dll, I decided to release a beta version first. If you can test the new version, your help would be much appriciated. If you give feedback, please try to explain in detail, what you did and maybe how a problem could be recreated. Important information is device or volume mode, error codes and the process you tested in general. Thanks in advance to all beta testers.
