Xinit Error-Remote Host

[vedanth]

Hello
I had installed Xfree86 for connecting to a remote host , for simulation as a foreground job in my PC. I have been noticing that the X window remains open for about 6 hrs , after which it disconnects itself automatically(the Screen is Still and doesnt work ..if i move the mouse of the X window the applications inside disappear and no X window Icon is found .) from the server and my Job is lost.
Also,interestingly ..my internet stops functioniing at the same time ..the X server connection is lost.
so..I have to close the X window of the cygwin to make my internet work again

I tried downloading the new versions of cygwin, reinstalling X free86 and window Makes 0.80 thats available...but couldnt resolve the problem
Do you see the problem ?

Thanks
