weird bug?
 

i have an hp vista comp and when im playing potco sometimes ( usually, ironically, when im having the most fun) the screen turns all grey and say potco has stopped responding! Also, sometimes when i log out, it goes back to my desktop instead of the potco menu. plz help.

they are called "Vista Credits" Please insert 25 cents for the next 30 min play lol jk. it sounlds like you need to update your video drivers or need more ram

my friend has a vista CP that does the same thing, if you have dell support center, try checking drivers and downloads
