Do you have it available and can test how that program feels when resizing on your system? In my setup I only get some light flickering at the scroll bars with buffered_drawing=2. Whereas I see heavy flickering with buffered_drawing=0. Do you see any difference between buffered_drawing=0 and buffered_drawing=2? Cheers, Johannes

Looking in the openssl source, that's just: int ssl_undefined_function(SSL *s) { SSLerr(SSL_F_SSL_UNDEFINED_FUNCTION, ERR_R_SHOULD_NOT_HAVE_BEEN_CALLED); return (0); } ...which is no surprise at all. I thought it might at least tell me which call was disliked.

New developer!

by jcid＠dillo.org

Hi there, I just wish to introduce you to Mr. Per Andersson, a senior developer with TCL/GTK/GCC/GDB backgrounds that's willing to help the project. @Per: if you want to introduce yourself to the list, here's a perfect spot. We've had some emails and he'll start working on debugging some problematic pages (I already sent him a though case), please try to answer any doubts or requests he may have during this period. TIA. -- Cheers Jorge.-
