As the users know, in the (old!) HTC P3300 we had a command to switch Portrait/landscape. With the new "accelerometer" generation HTC decides to take it off this command and (i suppose) replace it by the accelerometer reactions. But HTC doesnt give the correct use context and only the web browser run in the 2 positions. On the WWW we find Gsensor or others free softwares witch solve this. But its not realy good. Only some softwares switch right : WM microsoft office, files explorer... Starting portrait they switch full size in landscape. In others applications and B4ppc .exe the form is not refreshed when we switch (moving it). We keep a part of screen from portrait moving in landscape position and reverse. The only way to have a good run is to pass first by the file explorer, turn in landscape and selecting B4ppc .exe, then its running fine full screen. Its seem not a B4ppc QVGA option problem, it appears also with others softwares. ?? Is there any hidden microsoft flag or something to add in B4ppc to kill this portrait/landscape problem ?? Maybe a special refresh function ... I follow and try all works on the mysterious dll in the forum (and Web) which gives acces to the accelerometer. For Information, on HTC Touch Pro, you could find the UP DOWN RIGHT LEFT... move positions information in the register-Key : HKEY_LOCAL_MACHINE\Software\HTC\HTCSensor\GSensor key "EventChanged" See attached file which read it, enjoy.
