I expect that you are talking about the old Mauku 0.x for legacy devices (like N810). The touch screen may temporarily lost the contact while scrolling especially if you are using a screen protector. Thus, the software will receive separate clicks instead of continuous drag. It is related to hardware, not software. The upcoming Mauku 2.0 application for Fremantle does not have that issue. In addition, it will have a lot of new nice features... There is a thread about Mauku 2.0.
