In Windows, when you scroll up and down, it scrolls up and down:
No matter if your mouse hovers a combo box on the way.
In FlexSim, when you scroll up and down in the properties, it is supposed to scroll up and down... except if your mouse hovers a combo box on the way.
In the example below, my mouse is initially next to the Break To field. I scroll up, and then it accidentally changes the walk animation, which is of course not what I wanted to do.
In trainings, we have seen numerous times beginners being trapped by this kind of behaviour. They changed a setting in a combo box without realising, only to encounter a problem they didn't understand later on (ex: changing a task executer's offset behaviour).
If you also think that this is a flaw that should be fixed, please vote for this idea.
