Why is the mousewheel time-scrolling feature gone in PLECS Standalone Scope since Version 4.5?

Since Version 4.5 of Plecs Standalone it is no longer possible to scroll through the time axis of a scope view (when zoomed in to a section of the total simulation time) with the mousewheel. With Version 4.4 it still works fine. Is there any setting to enable this feature again?

PLECS 4.5 uses a new version of the Qt framework for the implementation of the graphical user interface. This new Qt version features a unified support for various input devices (mouses with scrollwheels, magic mouses, trackpads, trackballs) on various platforms.

A side effect of this unified support is that the mouse wheel now operates on the y-direction by default. Depending on your platform, you can make the mouse wheel operate on the x-direction by holding a keyboard modifier (typically Shift or Alt).
