Beta 16 is now out, with some hopeful fixes for various issues. To be honest, some of these bugs have been truly nasty to fix; I'm having nightmares hearkening back to the days of the Big Box VLC stability issues.
Anyways, here's what I've changed/fixed for this beta:
Added LaunchBox.Next support for "minimize on game launch" and "restore on game exit" options
Fixed LaunchBox.Next side bar combo box and search box not sizing properly for custom fonts
Added significant debug logging information for .Next window events (to provide better debugging information for freezing issues on some systems)
Changed the debug logging to use a timestamp instead of a GUID in the file names (for easier navigation in debug logs)
Forcing debug logs to be enabled for all beta versions (see below)
Added a missing, thought-to-be-unused DLL reference, which could possibly be causing the stability issues (though that's a shot in the dark)
As described above, I've made some minor changes to the debug logging system, as well as force-enabled it for beta versions. This means that a new LaunchBox\Logs folder will show up that logs various debugging information that can help when troubleshooting things like crashes. Each time LaunchBox, Big Box, or .Next are started up, a new file will show up in the LaunchBox\Logs folder with a timestamp on it, so you can easily find the latest file. In the future, if you experience a crash with a beta release, please post your debug log file here in addition to any other error messages that you have.
Thanks all, please let me know how this beta fares; specifically, I'm most interested in any crashes that you get.
