Thank you for your help. The local library has ebooks only in Adobe Digital Editions. I will ask them about eReader or Mobipocket in the future. I have eReader on my TX and use it occassionally. Again thank you for the websites.
I understand from postings that Palm sold the software to another company and will not be updating the TX software for Windows 7 64bit. Right now I can Hotsync using a wi-fi connection and Palm suggests using bluetooth.
I think the real issue is Adobe went to Digital Editions, which is OK. However they did not update support for the Palm TX, which I think is the Adobe Reader for PalmOS, with the new encryption being used in the Digital Editions.
Again, thank you for the suggestions. I will approach the local library to expand its ereader support.
