<p style="margin:0in;font-family:Aptos,sans-serif;font-size:11pt">Michalis was informed of the last two watchlist errors and reportedly has already fixed them. Many of the other warnings are also fixable if the test program is improved to use actual
file addresses instead of pseudo-urls. Progress steadily continues… the only “really bad errors” are the ones you don’t know about!</p>

<p style="margin:0in;font-family:Aptos,sans-serif;font-size:11pt">So X3DJSAIL is excellent for plain-old Java handling of X3D, and keeps getting better. Again thanks to John and Michalis for their contributions to identify problems that are now fixed.</p>
