QLab 4.6.4 Release Notes
Fixes a bug where cues duplicated in a cue list using option-drag did not retain their cue targets.
A crash in the Inspector that could occur when a Fade cue that targets video effects is retargeted to a cue that does not support video effects.
An issue where a Fade cue did not always correctly update its broken status after changing the cue target.
Resizing the Inspector when it is in a dedicated window now works correctly on Catalina.
Internal OSC queries will now format numeric values correctly for locales that use a comma as a decimal separator.
