Thanks for the extremely fast answer - it was about what I feared to hear. It would have been more pleasant to hear about a configuration trap I stumbled into - so it depends on how to define "it helps". My problem is, that I try to develop a "CCD" Camera for astronomical purposes (not really CCD for the moment as I want to try a CMOS imaging sensor). The control software is running under X11 (a very early version can be found on my homepage http://www.brunsteinobs.de.vu/, an update about the project will be done after a short introduction on a meeting in Mai), but the hardware programming environment uses Windows - so I was hoping to use cygwin and X11 to run my control application and nedit to test changes in the hardware. Here at work I use the system to monitor and configure our server and gateway... Anyway: is there any cheap workaround with free or at least cheap server software apart from MiX? Xwin32 runs extremely well but is much to expensive for being used only once a week as a private person? Apart from that: All programmers supporting the cygwin project did a great job. The whole system is getting better and better... I do not much about X-Server internals or Windows internals - but if you need a guinnea pig (hope the spelling is right, I just mean someone to be willing to crash his system - after backing it up) to run some tests, feel free to contact me.
