Only negative

[kik222 1]

I also made a huge mistake and updated my mac to 10.3.7! I haven't noticed anything positive yet.
But the negative is full!
1. The word document preview is gone
2. The ability to select all notes for export has disappeared.
3. When installing the system from the appstore, the system does not start - it requires access to the keychain and crashes.
4. When inserting an attachment (via Insert - Attachment), freezing is noticeable.
5. The system has lost the ability to "share", which is very sad.
Is it safe to downgrade?
