I use 1Password latest versions on iPhone 4, iPad 2 and Windows 7 all synchronized using Dropbox. After editing a secure note on the iPhone and saving it, the entire note just disappeared and deleted. I went to the iPad it was still there but as soon as it synced with Dropbox it was deleted as well.
Is this a known bug?
In the interest of full disclosure, my iPhone 4 is running the new iOS 5 operating system. iPad 2 is running iOS 4 and WIndows is WIndows 7.
