impossible to select some tables on many databases

Hi,

My site has 3 databases (1 for WP, 2 others). It is impossible to select some tables in each of them: in this case, only 2 databases are backuped; the WP database and only one of my “other” database.

The problem is on the “Generate Backups > Database Option” tab: You cannot expand/develop my 2 “others” databases (= seeing of the tables names to select some of them); as soon you select a one of them, the other is automatically reduced/shrinked, and the list of its selected tables is not kept.

Regards,
Michel.
