ok im not sure if its just me or what but when im on xpg sometimes half of my screen is black for no reason the only way to get rid of it is to refresh page but keeps coming back when opening a new page but not all the time anyone else getting this?
Which internet browser do you use ?. Might need to be updated. I use google chrome sleek , fast and clean interface.
Is your java upto date check it also flash for internet , sometimes html links (pictures , png) cause errors just clear your cache internet browsing history try then,
Then maybe your its your internet provider that isnt fast enough and it might not be loading the site proberly on your end.
