Hey, Just wanted to let you guys know about a bug in lesson 14: there's a place in glPrint() where the gmf array is indexed via the character value: for (unsigned int loop=0;loop<(strlen(text));loop++) // Loop To Find Text Length { length+=gmf[text[loop]].gmfCellIncX; // Increase Length By Each Characters Width } Where text is defined as: char text[256]; The problem arises when you have a character value greater than (decimal)127. Then text[loop] becomes negative, since char is signed, and the program exhibits memory problems. One bug fix is to cast it as an unsigned char in the index: length+=gmf[(unsigned char)text[loop]].gmfCellIncX; This bug won't be evident unless you plan to use characters outside of the normal ascii range, of course... cheers, Fritz Renema
