Both devices, track pad and Magic Mouse behave some kind strange. Against the standard mouse action, (eg: press to select, wipe two finger to move - track pad- ) the gnatt chart seems to jump a little nervous to left and right.
OS X vers. is 10.15.2
It seems, no one has a clue for this behavior. Working with the software get really frustrating, if there are one than one handling philosophy at one desktop. The task pane handles the mouse action as designed, the gantt pane does it different. If you just use the Magic Mouse like normal (wipe gesture), the pane jumps (or rushes) undefined. I really can’t believe to be the only one having this problems. I’m using a MacBook Pro, meanwhile sw 10.15.3. Or, on the other hand, is there any upgrade in progress?
