Backup via mySQLAdmin - character set problem?

[Larry Bradley]

Using mySQL server 5.0 on a Windows system, using myIsam. I have a "users" table that has the data encrypted by my program. When I back up the "users" table alone, the INSERT statement data is correct. If I backup the entire database, and look at the "users" table data, the insert statement data is different (and incorrect). Using "normal" backup option, and the backup options are the same for the two cases.

If I do the same thing on my Ubuntu system, all is well.

Something weird is going on. Why should the entire database backup and a single table backup give different results? What should I be looking for?

Thanks
