new WM6 750V trouble

[ir803]

I've just got my new 750V from Vodafone with WM6 to replace the 750v i had with WM5 and already there are a lot of things different. With my old phone you could safely put it in your pocket with dialling anyone as you had to press a two key combination to unlock it, the new phone activates by pressing just one button and therefore always ends up coming out of my pocket asking who i want to call or text or trying to open a program. Is there a way of changing which key/keys turn the screen on?
next..I used hidelogo and vjtoday on WM5 but on WM6 hidelogo does nothing although I've seen screenshots by other people who seem to have it working??!!?? vjtoday rmoved the bottom bar BUT it comes back on its on every now and then for no reason.
I'm struggling to find anyone who has WM6 on a treo to helps with these issues.
