Hi -- I have just had to uninstall open office because downloads from overdrive [public library audio books] are also odm files, and there appeared now way to have the overdrive media console open up -- the defaults [Win 7] were correct but the system automatically wanted to create open office files. This is why I've had to uninstall a very good word processor.
I don't know what the solution is ... unless using a flash drive or external hard drive will solve the problem. Toby Fouks
