DISPLAY is set in the Windows environment as well; cygwin must have done 
this for me, since I didn't do it manually.

I did some more digging, and here is what I find. If I start bash from a 
Windows CMD prompt by simply typing:

	cd \cygwin\bin
	bash

And then I type:

	./xterm

bash does not complain, because it finds xterm.exe in the current 
directory, but the xterm fails to pop up.

On the other hand, if I start bash as follows:

	cd \cygwin\bin
	bash --login -i

And then I type:

	./xterm

then the xterm pops up as expected.

The difference is that --login -i directs bash eventually to read 
/etc/profile, which adds cygwin dirs to the path. So as Morgan thought, 
this is somehow a PATH issue. However, I added c:\cygwin\bin, 
c:\cygwin\user\X11R6\bin to my Windows path, and the chere still does 
not pop up an xterm. (Note that adding these dirs to the Windows path is 
not an option for me anyway, as it causes me a lot of DLL-hell type 
problems).

Do you have any more suggestions what I could try? Thanks again for your 
assistance!
