Using the "View Log" menu option, you can view both these logs and copy them to your clipboard for inclusion in a support post or email.
When the Viewer opens it shows by default your current running log, wsalink.log. Pressing the "Swap" toggles over to adblink.old.log. Pressing "Swap" again toggles back.
Thus you can toggle back and forth between wsalink.log and wsalink.log.old
If you have questions or comments, please email jocala@jocala.com . wsaLink produces a log file, wsalink.log, with each run. Include it in your email if you're having problems.
