Upload panel errors

I wish to know, how do i fix the upload panel of my wordpress blog, the first time i uploaded a picture, it was fine, the other day when I had to upload a pic, the upload went fine, but when the image appeared in the browse area, onclick, I couldn’t see the menu, I wonder why this ha sbeen happeneing, I tried to access from two different locations but to no avail, I even tried re-uploading, but noresults, now I have two copies of the same file on the server, but it’s not worth, and besides, I cannot delete those uploaded file through ftp…
any help will be of great appreciation
Thanks and Regards
