guero, go over Winks suggestion along with gamegamegame. They have given the right solution direction to fix your problem. It could be me, but I think your inferring the wrong context of their suggestion due to a language barrier.
Wink suggestion has nothing to with platforms or landscape. It's a guide to just handling any screen size resolution. The help is now there it's time to do your part :) good luck :)
Thanks so much your interest.actually i cant understand screen sizes on c2 so i seek a exact way <img src="smileys/smiley1.gif" border="0" align="middle" /> but as you said I will try Wink's solution soon and i will write result.Thanks so much again <img src="smileys/smiley1.gif" border="0" align="middle" />
