I followed your advice and the problem is fixed. I don't know whether it will happen again or not. From one point of view, I'd be glad to have some serious problem that would need replacement, because I ,maybe I could pay the price difference and get the VA7. But on the other hand, I can be without keyboard for a maximum of one day and a half, which makes it rather impossible to deal with a replacement since I live on an island and I'd have to wait many days for my keyboard to be sent and a new one to arrive.
