Well, I think the incriminated code is in Amaya/thotlib/dialogue/openglfont.c the p2() macro/function If you could try with : int p2(int p) { p -= 1; p |= p >> 16; p |= p >> 8; p |= p >> 4; p |= p >> 2; p |= p >> 1; return p + 1; } otherwise, identical, formulical, but VERY VERY VERY slower and surely the one that works on non-x86... : int p2(int p) { return 1 << (int) ceilf(logf((float) p) / M_LN2); } or finally the slower than snail one : int p2 (p) { return p*p; } - If you know an optimized version of p*p on non-x86, feel free to try there - -Paul
