<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi everyone,<div><span class="Apple-tab-span" style="white-space:pre"> </span>As of a few days ago, the registration-verification certificate that has shipped with every version of Chimera for the last ten years expired. Consequently, any Chimera use after that would bring up the registration-request dialog regardless of how recently that version of Chimera had been registered. On top of that, the expired certificate caused new registrations to fail, so all you good people who were trying to help us out by registering your versions after this bug appeared were stymied.<div><span class="Apple-tab-span" style="white-space:pre"> </span>We have just released Chimera 1.5.2, which has a permanent fix for this problem. You can download it from:</div></div><div><br></div><div><a href="http://www.cgl.ucsf.edu/chimera">http://www.cgl.ucsf.edu/chimera</a></div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>For users who prefer not to upgrade immediately, we expect to have a solution for existing older versions in a week or less. We will send another email with details when that solution becomes available.</div><div><br></div><div>--Eric</div><div><br></div><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 16px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><div style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; "><p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="5" style="font: 16.0px Helvetica"><span class="Apple-converted-space"> <span class="Apple-converted-space"> </span></span>Eric Pettersen</font></p><p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="5" style="font: 16.0px Helvetica"><span class="Apple-converted-space"> <span class="Apple-converted-space"> </span></span>UCSF Computer Graphics Lab</font></p><p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="5" style="font: 16.0px Helvetica"><span class="Apple-converted-space"> </span><a href="http://www.cgl.ucsf.edu">http://www.cgl.ucsf.edu</a></font></p><br class="Apple-interchange-newline"></div></span> </div><br></body></html>
