I have been informed that this is okay. Is there is any documentation thatmentions this. I looked in the manual, but it doesn't mention anything like this.

	I hope that the answer will help, if you have still questions, don't hesitate to ask me. All the best, Late Never say never, think in solutions, not in trouble......
