Because mIRC itself never sends scroll messages to the MDI client window. It's not up to Khaled to modify mIRC to fix bugs in other software. It's up to your touchpad manufacturer to fix their software to send messages to the right window.

Besides, if K disabled scrolling of the MDI child window, then people would just complain if they actually want to scroll that and it doesn't work.

The issue is with your touchpad drivers, not mIRC.
