Byculla,
1) Yes we have X-DEV working again. Song provided the fix as always, but it is given out on an individual basis right now as opposed to a new version download.
2) We have not restarted sales of X_DEV. Yong is working on a silverlight web based application for X-DEV. He says it is labor intensive and will take a few months to complete. I can't give you all the details but if he incorporates some of the ideas we have imagined the product will be extremely cool. Intraday quotes in 1, 5, 15, 30, and 60 minute intervals for day and swing traders is one idea that we'd like to accomplish for example. A screening tool is another and so on.
3) Rule #1? You will have to clarify please. I'm not sure what you mean.
