HMI with different resolution

HMI with different resolution

I have a project (6.22 sp1) for hmi (wince 5) with 800x600 resolution; now we have to run RT on a new hmi (wince 6) with 1280x800; I  set this new resolution in  "Management screen" in editor project but some graphics present on the screens on RT on the new hmi are not displayed 

Any suggestions?
