<DIV><FONT face=Arial size=2>I am running release 2304 of Chimera under
Windows XP with service pack 2 on a Dell Inspiron 9300 laptop. The image
disappears from the screen for no apparent reason. With
the structures I am currently working on, this has become frequent and
often occurs after just a few seconds when I click anywhere in the Chimera
window.</FONT></DIV>
<DIV><FONT face=Arial size=2> </FONT></DIV>
<DIV><FONT face=Arial size=2>I have found that if I use Model Panel, I can
get the picture back by clicking the 'Shown' box to remove the tick mark, then
clicking it again to re-insert the tick. But the picture soon
disappears again. </FONT></DIV>
<DIV><FONT face=Arial size=2>Occasionally, it doesn't disappear
completely, but part of it collapses, or spurious long lines
appear.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I had the same problem with a previous release,
2184, and was disappointed that upgrading didn't fix it. I can find
no mention of anything similar</FONT><FONT face=Arial size=2> in the
documentation or email archive. Can anyone suggest a possible
cause?</FONT></DIV>
