Hi there,
I have been able to use Chimera many times in the past, but now when I
try to run it, a dialog box pops up and I get get any further. In
fact, it seems to be spawned infinitely and I cannot close it. Here is
the message: "Class DBPuppet.AC_KEY_ERROR'> Can't open web info file
for reading". I don't know what has changed on my system to cause
this, it was working fine a week ago. Does anyone have any ideas? I am
using the most stable production version right now.  My operating
system is Windows Vista.

Hi Christian,
We have an open ticket (#8515) in our bug-tracking system for this, but I don't see any activity for it since it was opened.  The developer that works on that code is gone for a week and I don't see any simple fix for the problem myself.  If you feel comfortable editing the Chimera Python source code, you could make a small change to <your Chimera installation>/share/DNPuppet/__init__.py that might allow you to get work done.  Lines 450 and 451 should look like this:

      else:
          keyfile = self.getWebFile('w')

If you edit them to put a 'return' statement between them, like this:

      else:
          return
          keyfile = self.getWebFile('w')

then I think Chimera will work, though it might have trouble opening Chimera scripts from web pages if you do any of that.
I will add you to the recipient list for the open ticket so you get a notification when a real fix occurs.
