@ahua52, it seems that you have the Trial version connected somewhere on your page. Other versions don't have the code that adds these popup messages. You need to check all your files for the Trial version of the dhtmlxgantt.js file.
Also, starting from the 7.1 version, that popup message is only displayed in the top right corner, it not longer spams the whole right side.
