I've not tried a clean install yet, just checked for updates on a 6.6 install and let 6.7 install. After turning on Dark Mode, the settings warned me of duplicate hot keys. Looking at the list, there are two of each. Instead of uninstall/re-install I guess I'll just delete the dupes.

ALL of them. Plus, I can't really delete the dupes, only just pick them and remove the assignment. Maybe I need to wipe all of LogFusion and re-install. I upgraded another 4.6 machine and did not encounter the problem. Win11 was the only machine so far I've seen the problem on.

Fixed it. Just went into the registry and removed the entire Hotkey node. Starting LF again recreated the default hotkeys.

HKEY_CURRENT_USER\Software\Binary Fortress Software\LogFusion\HotKeys

Just now noticed the dupe keys showed up in a Win 8.1 x64 system. I think this was a system I'd never had it on before. Just FYI I guess. Same fix worked here.
