Cloud Overlays on world map

[elmerg]

I've got a 'baseline' working cloud overlay for RM2k3; I've got it working and moving using Show Picture and Move Picture events. However, there're two things:

1. It doesn't show anywhere but one of the sets of spaces that is listed.

2. When it loops back around, being a loop event and parallel process, there's a bit of a jump.

Any type of input or help on getting this to work in so far as developing a constant cloud-movement on the map would be definitely helpful. I searched the forums, but I couldn't come up with anything when I used the search terms 'rm2k3 cloud' and 'cloud overlay'
