Maps Expanding

[carp]

I seem to have developed a bug. I have WinSPMBT and WinSpww2. When I make a map in Winspww2 and transfer it to Winspmbt somewhere in the transfer the map gets screwy and no matter what it's origina width and height it expands out to the max 200 x
160. The expanded area is always 0 height and level terrain. The map expands out to the right and to the bottom. Is there any way around this? I've reloaded the games but it keeps happening.

Thanks in advance.
