As I begin working on my site, the cursor becomes one with 4 arrows

As I begin working on my site, the cursor becomes one with 4 arrows pointing towards 9 & 3 and 12 & 6. Then as you roll the cursor over the webpage you are working, it moves everything as well as automatically scrolls down. What's the problem? It does this everytime I use my laptop in my car using the Verison 4G LTE Jet Pak? HELP!!!!
