Odd OpenFileDialog Behavior Filename Scrolled To Left

I set up an Openfiledialog and put in an initial filename value (the last filename the user opened).However, when the dialog shows up, it is as if the filename has been scrolled off to the left.I only see about the last 10 characters of the name, even though the filename field is big enough to show the whole name.It is also selected, which is ok - it means if the user types a name the value will replace what I've put there, which is reasonable behavior.How do I control this 'scrolling'?I call it scrolling even though there is no scroll bar.If I click in the field and use the left arrow key I can back up to the beginning of the filename - the filename gradually shifts into view about 10 characters at a time, until I reach its beginning, at which time I see the entire filename in the filename field which is how I'd like to have things when the opendialog opens.
