Ok i've found the bug. Can you fix it in next release, pls?
In Scheduler.js function gMouseMove there are these lines
if (typeof(DayPilotBubble) != 'undefined') {
DayPilotBubble.cancelTimeout();
if (DayPilotBubble.active) {
DayPilotBubble.active.delayedHide();
}
}
If tthese lines are removed all is working like before!
