Hello, Thank for the comments. Actually, it seems to be strongly related to xmgrace. If I open 2 times xmgrace, Xorg.bin move up to 99%! In addition, some functions of xmgrace are very slow while it was OK a while ago, may fc19 or fc18. I could report a bug, but I would like to be able to send instructions relative to the reproducibility. =========================================================================== Patrick DUPRÉ | | email: pdupre@xxxxxxx Laboratoire de Physico-Chimie de l'Atmosphère | | Université du Littoral-Côte d'Opale | | Tel.
