If you are using Easy mode day to day(big simple icons screen below), you don't want to be asked to change to Home. Likewise if you are on the standard Home Mode you don't want it to keep asking you to change. There have been periods in the past where this pop up happened too often. It should not do, but for whatever reason it is now pestering you.
In a previous thread on this, 1 person had success with changing to the other mode then go back and change it back again. Settings - Device - Easy Mode.
A better suggestion from @Z06mike was to go to both Touchwiz apps in Settings - General - Applications Manager - swipe left for the All list, then press Clear Default of the version you Don't want.
Of course taking the battery out first may cure it also, as well as other suggestions here. And you don't need a Limo driver to do it for you.
