Hello, There was no comment on my proposition below, should I consider that it means people are fine with it? :) Samuel Samuel Thibault, le Fri 29 Feb 2008 12:08:07 +0000, a écrit : > Sometimes the backend of PVFB knows that it doesn't need permanent > refresh, when the window is minimized for instance (no refresh at all), > or the administration tools know that the window is thumnailed, and so a > slow refresh rate is fine.

A period of 0 would mean that no refresh is needed > (e.g. minimized window) _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
