I was just using that as an example the shows the bug I saw. With '+bs' on Radeon, the (left-mouse-click) menu is blank until you move the mouse pointer over each of the menu items. > Would disabling the DRI when backingstore is enabled give the semantic > consistency you're looking for?

I commented out the 'Load "dri"' and 'Load "glx"' lines from my XF86Config file and got the same behavior. -- Smile! http://antwrp.gsfc.nasa.gov/apod/ap990315.html _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
