Re: [perl-win32-gui-users] Avoid the appearance of a "frozen"

[Octavian R. <ora...@gm...>]

Thread safe or not, unlike a Win32::GUI object, a $dbh object can't be 
shared among more threads.
Does anyone know why? Because of DBI, of DBD::mysql, or because a database 
connection can't be shared among more threads, or something else?
