I've notice a big problem with cyberduck, luckily i back up my files. But, while I was working customizing a wordpress website I notice that somehow it messes a file up when saving or uploading it. For example, I was editing a .css file and when i view the page again its like if it was not reading my file, and you will see cyberduck not even reading the size on the file upon saving it. As soon I add a backup file containing the same info it works again, this happens when i edit any file, it just messes the whole site up, after 1 hour having to reupload from my backup i had no choice in reinstalling 3.5, luckily i had the program backed up in my computer. It worked perfectly after reinstalling 3.5.
