Laptop "internal" mouse
By experience, I found that the "internal" mouse is quite easy to use and very effective. I just can use one finger to operate it in many cases, but in some other cases such as "click and drop" or "double click", I still found something "stupid". Sometime, accidentally because of the sensitivity of the "internal" mouse, I move a directory to another place, or execute something that I don't want to execute.
Did you have the same experience like me with the "internal" mouse at the first time you use it? or may be you have some tips or tricks using "internal" mouse that want to share with me? please let me know.
