Mouse Issue with Android Tablet with physical keyboard/touchpad combo

I am having a great deal of difficulty using the Android App for unattended access of other systems.  The way the mouse works on the app when using the keyboard/touchpad is almost unusable.  Most of the time it doesn't seem to work.  Does anyone have any experience using such a setup?  It works fine with my laptop, and it is also working just fine with my desktop.  The table however seems to not work properly with the attached keyboard/touchpad designed for this tablet.
