BTW I am not a wine developer, I am a user. I am also not a programmer. I am very technical but have different specialties. They do not include Linux. I am monitoring wide area microwave networks and finding the windows IP stack unable to handle several sessions of Ping plotter at the same time. Since I use Ubuntu on my desktop for web/email/openoffice jut fine I was hoping I could take advantage of the power of Linux to solve this problem. Ping plotter is a secondary tool as we have another system that also does this monitoring. But having two monitoring systems has great value for many reasons.
