15.Improved /drawrot, now faster and supports float values.
This is certainly the reason of your report.It seems that the new method to make /Drawrot faster does not work on win98.
Edit : of course i'm unable to reproduce this on my winXP, but i've tried, to use /drawrot on a corporate version of window xp and it works only if I use it one time.If I use it each second for example, the application is simply closed, no crash, no window report.I'm not considering this as a bug since it's with a corporate version of window.
