Sweet Home 3D and Macintosh G3, OSX 10.4.11 don't mix!!!

[rblue]

[:(] I downloaded the installer package, ran it and indicated that I wanted it loaded to a volume (not the same as where the system lies) where all my third-party applications reside. I have Java 5 update loaded as well. I click on the application and it does launch, it bounces on the dock twice and the menu bar shows Sweet Home 3D - but only that and then....nothing.

I ran the console program and this is what it recorded:

Can anyone help? This program looks terrific and I was looking forward to learning and using it... [:-/]

I tested Sweet Home 3D 2.4 beta under Mac OS X 10.4 yesterday, and it worked with no problem (it wasn't on a G3 though).
From your console message and a request similar to yours, I guess you're running Sweet Home 3D from the Java Web Start link and not from the installer package.
Try to run it from the installer version.

I tried by launching the installer version. Its started as before, this time a color modal window comes up with Sweet Home 3D, then it disappears. And then....nothing, as before.... [:-/]
