Hello,
Thank you but....
1. it really helps a lot when you send bug reports to bugs@xxxx
Sending it to mailing list causes additional work for me
since I have to sort e-mails manually.
2. Please include bug report generated by AmiBroker because
it includes valuable information (crash address for example)
that is ESSENTIAL to trace the bug.
Best regards,
Tomasz Janeczko
