The Google Gadget Editor really is a stinking heap of dung. Amongst the things it gets wrong:

• After you open a source file for editing, you cannot delete any characters or lines until you have inserted some.
• Indentation is completely up the spout.
• Sometimes it adds two blank lines when you hit return in the middle of a line.
• Worst of all, when embedded in iGoogle, it sometimes refreshes of its own accord. When this happens, it resets the file you are editing to a default one, and if you had any unsaved changes, they are discarded. At first I thought this was only happening when I left the iGoogle window idle for a while, but I've also had it happen in the middle of editing a file, literally between keystrokes.

It should never have shipped in this state.
