Little know fact (well, not really) is that you can initalize
your array as follows.. 

bool scrn[640][480] = {0};

You could initalize every variable this way as well (Even 2D, 3D... nD
arrays) by just putting a comma (,) after ever variable. 
Ex.

bool foo[2][3] = { 0, 1, 0, 1, 0, 1};

(although most people tend to do the following to make it easier to
visualise)

bool foo[2][3] = { 0, 1, 0
                   1, 0, 1};

(Could someone tell me if I'm wrong but I think this is possable.)

Note though, by default if you initalize one variable of the array but not
the rest, the rest get set to 0 (zero).  So....

bool foo[2][3] = {1};

only sets the first item of the array to 1 but the rest to 0.  As for how
efficent (sp) this is, I don't know.  There could very well be some un
desireable affects to this (which I would love to know myself)  but it
works.  

     As for you current problem, I have no idea why it's not looping
properly.  Is what you posted an exact code snip?  How about walking
though it with rhide?
