Updated with minor error fix - not adjusting new screen width IMMEDIATELY when switching between landscape mode and protrait mode.
Also, for those who haven't noticed, I created CAB file for easy installation/uninstallation. Besides,
Pablo216 and
Kendawg, you don't need to use special version anymore. Through the RegTweak utility, you can choose what mode you want to display.
The new zipped CAB file is update in the first message of this thread. Enjoy. :)
