alt tab + game freeze + sound continues

[Toehammer]

try going back to your EQ window and hitting Alt+enter... that will make EQ full screen and usually the graphics will reappear/reset.

The same thing as you are describing happens on my computer sometimes... I think it is something to do with the graphics card's capabilities. For example, if I open Google Chrome, there is usually no graphics freeze in EQ, but if I open another game, say Diablo 2, then when I alt tab back to EQ it is just black... then when I alt tab, graphics restored.
