GPS Data Logger Software - BT747

IMPORTANT: JAVA 7 (1.7.0_51) now requires that BT747 is signed with a TRUSTED CERTIFICATE.
You can also lower the security level of JAVA 7 to 'medium'.

BT747 is signed since version 2.1 with a certificate.

To do so, I bought a trusted certificate (provided by a trusted authority) for about $300 (valid a few years).  Received it on Jan. 17, 2014.

Thank you (!) to the user that already contributed to help cover the certificate cost.

Given that sourceforge alone currently reports more than 300 downloads in one week, the cost could be covered in at most one week if every user contributed just $1.
