Re: NX client with root graphics

Stan,

I cannot understand your conclusion. My conclusion is that you cannot reproduce
the problem that you initially reported ::) and from your original description, most of us understood that it was probably a problem with the software in your NX box.
Let us know if you can reproduce the problem in a systematic way.
