...lt. I'm no x11 guru at all, but the bug report referenced gives a plausible explanation of what might be the cause. That bug-report also contains a patch to fix the issue. For all I can see, that patch should still be applicable to current sources with only minimal adaptations (DevDesc -> newDevDesc, etc.). Is there any chance this will be taken care of in one of the next releases? Or are there issues that make inclusion in soon-to-come releases unlikely? I'm asking, as in the latter case, I'd have to look into different solutions for my application. Thanks! Thomas Friedrichsmeier

Hello. I'm looking for documentation about the graphic device model in R. I would understand it in the details, but it seems a bit complex :) Thanks for any documents which will help me. Laurent
