I notice that if one sets an environment variable from outside while R is
running it as no effect at least under NT. The same goes for cmd.exe for
example, if you set some environment variable via the control panel it will
not be visible to cmd.exe this time around. If you restart R you will get
the new environment setting.

I've managed to get some of the TclTk demos to run but some don't run to
good. At least not all of them:

> demo("tkttest")


        demo(tkttest)

Type  <Return>   to start :

> demo("tkfaq")

Shows the window with the faq and starts complaining with errors as soon as
I try to scroll or close it. I had to quit R to close it!

> demo("tkdensity")

Seems to work fine.

> demo("tkfilefind") & demo("tkcanvas")

Seems to work fine also.


Just to make sure, I'm not complaining here, I just report what I observe.

Regards.
