Hi Martin, Sorry for any inconvenience caused by my previous email. I just didn't know whom I can ask for help in Microsoft. I have been a member of this mailing list for over 2 years, and I realized that you are one of the most studious person here. When problem happens, I tried to get advice from you. This memory leak issue happens only after WinME QFE # 25334 is installed, and we believed that QFE code does contribute to this issue. Since we are considering to merge this QFE into our driver installation package, we need to find out the root cause. That is why I was so rash. Sorry again. Anyway, I will post my question on mailing list again. Hopefully somebody can give me a clue. Regards, Skeeter __________________________________________________ Do you Yahoo!? Yahoo!
