I have not test this function under windows 2000 yet, but at a first use under windows 95, this problem occured.
Maybe it's just something with my windows 95, but anyway I thought I'd better mention it to you. I'll test this under Windows 2000 too, and let you know also about this.

Thank you for your Attention, and I'd like to thank you for the programming language you support. I think it's the best of all the web programming ones I've learned till now. Very powerfull, and very friendly to C's and perl's developers.

Thank you again,
