Network Programming in .NET

When compiling (ant build) a BlackBerry Webworks project, I got this error: error 907 icon data is too large.

The icon was about 42K. I discovered that, I had created the Icon with Fireworks 8, which had somehow jam packed the PNG full of layers, metadata, and larger images, that I had used to create the icon. I discovered, that if you export as image only, or select batch process, select export, then custom, the png 32, then it drops it down to a few Kb, and the build goes ok.
