pgAdmin Beta 3 problems

I seem to have encountered several problems with the latest Beta3 of 
pgAdmin. This was installed with the latest Beta3 Dev1 installer for 
PostgreSQL.

I had Beta2 of pgAdmin previously installed, which was uninstalled 
when I uninstalled Beta2 PostgreSQL.

1) The "Recent Files" menu doesn't seem to work at all any more. 
There was a list of files left over from a previous pgAdmin install. None 
of these worked. Even when opening a file then going to the recent files 
list it still wouldn't re-open.

2) Creating a new database on the local (Windows XP) cluster gave a 
"Locale: is invalid" message. I only typed in the name of the database 
and clicked OK. The default locale in the drop-down was UNICODE. 
When I selected something other than UNICODE and the re-selected 
UNICODE, clicked OK and it created the database OK.

3) It still gets the "dirty edit buffer" logic wrong. I have noticed that then 
I open a file it has not marked the buffer as dirty. I can navigate around 
the screen, making no changes and it is still OK. As soon as the edit 
buffer scrolls, with either the keyboard or mouse, the buffer is flagged 
as dirty and you are asked for saving changes when you quit.

Regards,
Gary.
