I believe it's relevant to the time the computer takes to generate or
display the graphics, because this issue occurs more often with graphics
with many points. Moreover, the computer on which I'm currently running
Rkward is sometimes short on memory (300M) and the hard drive is no so
fast.

Thanks, it works very well.

I noticed the same fact.

Thanks again, it also works fine.
Maybe the "refresh" menu item should tell the khtml kpart to reload.
