I've just tried adjusting the width (fixed pixels) for the task name in the
task summary view between 40 and 600 pixels and it's worked okay. I not
aware that this is a reported issue.
I'm having the same problem Peggy is having. I change the Task name width,
but the column doesn't move. I created another view for My Tasks only with
column "Task name", but although the column is bigger now, since is the only
one in the view, just part of the name's task appears followed by ellipsis.
