How to disable giveaway Pop Description window (ESGST) ?

Going to need a bit more to go on...
You can screenshot your screen and post it on imgur and then copy link to the discussion to clarify :)

short anser: you can't.

long answer:
some ppl make giveaways to promote stuff. at some point it was possible to disable those pop-ups. but without those , the promotions and the like wouldnt be viewed any more (even if its just milliseconds). this would be unfair to those ppl, so admin told the developer of ESGST to make it so it would still be seen.
so now those pop ups cant be deactivated when using the feature to have the enter-button on main page and the likes.

what you can do though... there is an option to make the repeated descriptions not pop-up (same description during some set of time wont show) as well as if there are only comments but no description
