hi everyone, i am running my notebook in 1280*800 resolution, often a baloon pops up saying "your computer is not at its optimal resolution of 1280*800 click this balloon to resolve the problem. I click this balloon the screen flickers as if changing resolution and it just pops back the same as before.

 

i click it to get rid of it but i know that my screen resolution is already set to that. it says so in the display settings, yet that baloon keeps coming up, what can be done?
