start wvga fix , then pick the smaller size 480x640 setting , then start Hava, either landscape mode or nonlandscape, but there should be a (menu)setting button in bottom left , you need to go in and add your hava info (name and password), then save changes, close hava after it connects.
Then go back into wvga fix and change it back to the higher wvga size, save and close wvga fix. Then you should be able to open Hava and then hit the button on the bottom middle of screen and it will automatically default and play with the settings you placed in previously. This definitely is the way to do it and if you follow these instruxtions it should work. You do need to make sure you uninstall the monsoon multimedia hava app from remove programs and then reinstall it (provided you have right version , look here :
