I don't think there is much you can do about that if you are using the mouse as a control device.
However, many tasks can be accomplished using .commands in the radio buffer. There should be a list of them in the Help section of the AH web site.
Unfortunately, it means you will have to get everything set up and adjusted before you go flying, but I don't know any way around it.
