scroll bar in quest helper disables jump function

[Raull]

I verry much enjoy your ui, i have a problem with the scroll feature disabling my jump though ( space bar will cause a drop down menue to apear) i"v seen that you can disable this function, but i like to use it, is there any way to simply disable the comand to the space bar and stop the drop down menue from apearing, and still keep the jump function operational.
Thanks.
