GSAK uses the exact same method to match the "found by me" as is does for your placed by caches.
GPX files don't actually contain the "date found by me" per se. GSAK gets this information by interrogating all the logs, looking for a found log that matches you.
What is happening in your case is that you have not identified yourself to GSAK correctly for this matching. (this would also mean that GSAK is not recognizing your placed by caches either)
You set how GSAK matches you via Tools=>Options, then correctly filling out the "Method for matching placed caches". Click on the help button when you open this dialog (the screen shown in the help file has hot links), or see this topic online here for more information.
Thanks Clyde. I had entered our GC.com ID (Mac and LaLa) on the line and had the "Use gc.com logon ID" radio button pushed. It seems to be working great now that I've changed it to the "Exact Match" setting.
One other quick question, will it look in all the logs for my ID or only so many logs back (the 5 or 6 it seems that are sent in the GPX file from GC.com)? I haven’t had any problems with it NOT picking up any of my finds, but I was just curious.
As with everyone else, the more and more I use GSAK, the more I appreciate the hard work you've put into it. THANK YOU!!!
