I'd say that you're going to have to get at least a bit more specific
before someone can offer any real advice. I've run an NX client on
my machine against cygwin packages 1.5.19 and 1.5.21 with no noticeable
problems. I've run version 1.5.0-106 of the NX client on both of the
above. I've run the current 2.0.0-98 against 1.5.21. But be sure you
remove all duplicate DLLs from the bin directory. I found the following
DLLs were duplicates with my installation:
cygcrypto-0.9.8.dll
cygz.dll
cygwin1.dll
cygminires.dll
cygjpeg-62.dll
cygpng12.dll
Really, it would be better to install, via 'setup.exe', all the packages
that contain the 'cyg*.dll's delivered with the NX client and then delete
all of these from the installation. That's more maintainable. But how you
handle it is up to you.
YMMV.
