One other thing you could try is to remove line 11 (%V|0|0|-|-|-|000000|-|). This viewport isn't necessary as far as i can see, but it is covering the whole screen, so it overlaps with the other viewports which can lead to unpredictable behavior.
If you want someone to test the WPS, then you have to provide the images along with the .wps file (and also tell the name of the used font).
