Messages sent using a third-party viewer disappear in the SecondLife viewer.

Description

I often switch between third-party and Linden viewers for testing or operational issues, but sometimes messages sent with a third-party viewer don't appear in the Linden viewer, or messages sent with a Linden viewer don't appear in the third-party viewer.
This often happens when switching between Windows and Linux.
I found that the cause is that the files recording the chat history are created separately.

For example, let's say there is a user called "Example.Account".

In that case, the following files may be created:

1. Example.Account
2. Example.account
3. example.Account
4. example.account
5. Example Account
6. Example account
7. example Account
8. example account

These files are treated as completely different files on Linux, so in the worst case scenario, eight different files may be created.

Is it possible to make the message appear even if any of these files exist?
