[Gnuplot-info] gnuplot invocation from Linux/Ubuntu GUI shell

[seb_kramm <seb...@ya...>]

Hello,
Excuse me for such a silly question that might be slightly off-topic, but:

I'm a Windows user that just switched to Linux/ Ubuntu flavor 10.10, and I'm confused 
with gnuplot (4.4) invocation from the GUI shell (Nautilus).
I'm ok with gnuplot generally, long-time user.
I have associated .plt files to the gnuplot binary, and when I double click on 
test.plt that contains:

plot sin(x)

I get the plot, the window is "alive" (mouse coordinates are shown), but I can't 
close it by pressing CR (or any other key). I have to kill the window (even closing 
it manually doesn't work).

Am I missing something ? If there's any Ubuntu users around there...
Thanks
