Hi again, its more font woes. I’ve figured out where I was going wrong with
my last problem, and now I have a new one, complete with memory leak! I’ve
included the routine to where I’ve isolated the leak (if i comment out
CreateSurface, no leak), but I can’t seem to figure out where I’ve gone
wrong. I then run the glFont demo and it has no leak. They’re both
identical. Any help would be great. Did i miss something? Thanks.
