Cursor is broken in Thunderbird.

[Daniel Carrera]

Hello,

After upgrading to Dapper Thunderbird started having problems with the 
cursor (maybe it's a miss configuration). When I hit the up arrow key 
the cursor doesn't go directly up like it should, but it goes to the 
beginning of the like. This is incredibly annoying. I have to press the 
arrow keys 30 times for something that should be done with 1 key press. 
Or I have to use the mouse every few steps which is just as annoying.

Let me give an example. Take the following paragraph:

"The European Union is a supranational organization[line wrap]
of 25 countries in the European continent."

Put the cursor after "Union". If I press "down" I'd expect to have the 
cursor just before "the", but instead it goes to the start of the line 
(just before "of"). More annoyingly, if I press "up" again, instead of 
going back to where it was (after "Union") it stays at the beginning of 
the line (Before "The").

Does anyone know why this happens and how I can fix it?  Is there a way 
I can return to the old Thunderbird? The old one was more stable and 
didn't have this bug.
