Hi Paul Davis , Thanks for your prompt reply ;
Can u tell me where exactly the changes have to be done? As u mentioned there is a fix in quartz ; can u elaborate on that ? where in the source code i can find it ? Could i provide a similar fix on DirectFB stack or should i use that the mentioned function in the appllication code itself ? Awaiting for your inputs... Thanks & Regards sv.
