You're right; whereas it takes a couple of seconds to open on 1.5.3, it takes basically forever on 1.6. I'll be opening a ticket in our bug database about this with you on the recipient list so you'll know when it is fixed. I hope it gets fixed in time for the 1.6 final version but if not then it will be fixed in 1.6.1 for sure.</div><div><br><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><span class="Apple-style-span" style="font-family: monospace; ">I am also noticing<br>that the latest version seems to launch more slowly and takes more time to<br>display BIG scenes (consider PDB ID = 1FFK).</span></span></blockquote><div><br></div>Well, this is actually a side effect of the VRML thing. I hadn't anticipated the direct opening of VRML strings when writing the new Rapid Access interface. Consequently, the text of one of the "recently opened" buttons is the entirety of the VRML string you opened! It actually only shows the last two curly braces, LOL. At any rate, showing that huge VRML string on the button is causing all the slowdown.</div><div><br></div><div>I have committed a fix for this latter problem and it will be in the next successful build. If the slowness is bugging you too much to wait you could go and edit ~/.chimera/preferences, search for "Rapid Access", find the first opening curly brace after it (start of a dictionary) and change the 'data history' list to an empty list.</div><div><br></div><div>Thanks for reporting this, BTW.</div><div><br></div><div>--Eric<br><br></div><br><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>
