Are you talking about using the site default clickable maps?
You could also always use the drop down menus if you are having an error.
Have you tried using the large map version to increase the size of the map? I'm not sure if this would make it easier for you to click the regions you are trying to.
I use clickable maps (Firefox add on) and not the site default clickies so I have no confirmation messages when deploying or attacking that pop up on the screen. Maybe this would be something you would want to look into: viewtopic.php?f=527&t=161049
