well your the only person I know with this problem, so theres no way of knowing how or when it will be fixed. if you can get it to open in Qstardict, i dont understand why it wont open anywhere else...seems like it wont open with the native nokia apps, but opens wit 3rd party apps. interesting. install abiword or leafpad and see it works there. Also try in the x-terminal.

Also, what country is your n900 from?
