Oh thank god. This is the default setting on Debian, and this bug has been driving me crazy.

I am also experiencing this bug (with SeaMonkey 1.0.5).
It is extremely annoying.

Still present in SeaMonkey 1.1.7 (Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.11) Gecko/20071227 SeaMonkey/1.1.7).  Has there been no progress on this?  Any suggestions on where to look for the problem?

Comment 4

[Andrew Church]

Confirmed that the bug does not occur when the use of Pango is disabled (and that the bug is still present in SeaMonkey 1.1.8).  It would still be nice to have a proper fix, or at least figure out whether it's a Mozilla or Pango bug; can any developers suggest where in the source code to start looking for the problem?

Still present in 2.0.0.22 (20090719)

I'm surprised this isn't a more popular bug.

Does this really only bug 4 people on the world?

I find it outragously annoying, after all, hasn't this character position in line during up/down arrow been a basic function of text editors for something like 40 years?

And this bug is open for 5 1/2 years? WTF?

[Andrew Church]

Preliminary testing suggests this is fixed in Seamonkey 2.0.3 (so presumably the latest Firefox as well) using Pango 1.26.2 on Linux/X.  Anyone else want to confirm?

I can confirm that it is also corrected now is shredder 3.0.1

Woo Hoo!
