I'm not sure what's going on with you and Mognuts.
I am even more confused! I had a think about it and realised as I am running Vista on this PC, that may be causing the difference. This morning, I booted up one of my other PCs , running Win2000, checked the Mognuts stats and sure enough, there they were, just as they should be. I then checked them on my Vista PC and lo and behold, there they were in all their glory and as you say opening them in Wordpad retains the formatting. So unless the utility has been updated overnight to make it compatible with Vista, it will just have to be put down to one of these strange glitches that happen now and then.
