Hi again,
regarding the problem of "perturbed plot" I mentioned, I found out some systematic behaviour:
- I plot something
- I save it into a jpg
- I get the cursor into the window and there it gets nuts...
scatter([0,1],[0,1])
savefig('toto.jpg')
==> then put the cursor in the plot window....
and this is systematic (so this does not seem linked to a change in the desktop finally)
