Cpu Hits 100% When Rendering

hmm…bit of an odd one this.
When rendering tunes my cpu hits 100% when saving in ‘best’ mode…i’ve tried all sorts to try and solve it with no joy.
Sometimes it cant handle it and freezes about half way through.
My pc spec is AMD Athlon XP 2500+ with 512 MB ram.
Ive run through the settings with a mate who has renoise too and set mine the same as his, but still cant cure this.
Any advice?

If you have 1.281 then just wait, you’ll get 1.5 beta very soon. That could do the trick.
