I've been able to reproduce this twice in a row. Second time I captured the logs.
Fresh install of MC18.
When the "auto-import" task shows up, click on it.
When configuring auto-import, uncheck all items except audio. Uncheck "Get cover art".
Choose the location where my music is stored (for me, it's the My Music folder in Win7's Libraries).
Click Finish to start the import.
While the import is running:
Tools-->Options
Under Audio, changed output mode to WASAPI - Event Style
Clicked Output mode settings, changed Hardware buffer size to 50 milliseconds.
Hit OK.
Crash!It's a pretty solid crash, too - on relaunch, the JRiver window is all kinds of messed up. Need to restart in order to fix. (I tried uninstalling/reinstalling, but that doesn't fix the window.)
I'll be emailing the logs to the address recommended on the Stability wiki shortly, along with a screenshot of what the app looks like after the crash.
Thanks!
[Edit] - Scratch that - just rebooting doesn't fix the window. I needed to uninstall, reboot, then reinstall.
[Edit2] - Wrong again! Need to change skin, quit the app, then restart to fix the window. This time I'm sure
[Edit3] - Seems like the import had nothing to do with the problem. I let the import finish, then changed the output mode to WASAPI event style and the app crashed. Corrected the title.I should note that I also have MC15 installed and configured to use WASAPI Event Style with no issues.
