gEDA-user: Strange user interface behavior with gschem-1.6.2.20110115

Sun, 04 Sep 2011 13:52:20 -0700 

Hello,

I have a strange usability behavior with gschem 1.6.2.20110115 (the version
that comes with ubuntu-11.04). I have attached a small schematic to
illustrate the problem.

In the attached schmatic, when I try to draw a net from U6-pin27 to the
gate of Q6, a little circle appears on the nearest pin, indicating where
the connection would be "autocompleted" to. But even if the circle appears
at the gate of Q6, at the moment I click to make the connection, it jumps
to the gate of Q4, effectively shortening pin1 with pin28 of U6.

I have not seen such behavior before. In fact, I have not seen such an
autocompletion-circle before. Is this some new functionality? Is there a
way to deactivate it? Or at least configure it to behave in a sane way?

In the attached file, I have embedded the parts to make sure that whoever
tries to reproduce, gets the identical parts.

Any ideas? Suggestions?
