Bug under Win32

Hello,

I am trying Mail::Box (v. 2.053, Win2000, Perl 5.6.1) and it seems it 
has s a bug:

When a folder is opened and closed again (without modifications, but 
rewriting it by "force"), the folder gets corrupted and an error message 
is printed for the last message:

"ERROR: File too short to get write message 12 (1872, 1928)"

I guess it Mail::Box makes a mistake when counting the linebreaks
(which are CRLFs here it seems - I work with Mozilla Thunderbird files). 
When I try to set the "lineSeparator" (as stated in the POD) for the 
folder I get:

"Method lineSeparator() is not defined for a Mail::Box::Mbox::Message."
	Mail::Reporter::AUTOLOAD('Mail::Box::Mbox::Message=HASH(0x2396c90)', 
'^M^J') called at C:/Perl/site/lib/Mail/Message/Construct.pm line 61
Mail::Message::AUTOLOAD('Mail::Box::Mbox::Message=HASH(0x2396c90)', 
'^M^J') called at C:/Perl/site/lib/Mail/Box.pm line 800
	Mail::Box::lineSeparator('test', 'CRLF') called at 
D:\Scripts\perl\test.pl line 45

Thanks,

Martin
