Thanks guys. Some info about this problem:

1- There are no text saved at all, on any of Xml files;
2- The problem isn't only about the text - some imported images disappears too, and the LO shows a red "X" on screen over those objects;
3- If I have some 4 or 5 objects from one or more big sketchup models, and some images and text, the problem occurs when activating the "hybrid" rendering on those objects - then some bitmap images "disappears" from screen - next time to try open the file, and LO shows this message then exit: "Microsoft Visual C++ Runtime Library - Runtime Error! - Program: (empty) - This application requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information". Even the debug window do not shows up.

The system is a XP64 still Sp2, with several GB of Ram, and LO never uses more that 1.5 GB.

btw, I starting reading Google SketchUp for Site Design: A Guide to Modeling Site Plans, Terrain and Architecture (the name alone takes up the first 12 pages of the book! 😉 ) yesterday and it talks a lot about importing CAD drawings and gives some really helpful advice on a couple different methods to through the cleanup process, as well as some various ruby scripts which speed things up. He also has some interesting ways of using a few tools that help with site modeling as well. I've only skimmed it so far but if you work a lot with terrain you might check it out. There don't seem to be many SU books out there yet so getting detailed info can be tricky, at least that's my experience.

arklandesign started a thread on the book here...

I have used both fx1400 (in a laptop) and the fx1500 in a desktop. Never had any problems with artifacts in either. The 1500 seems faster but I have no benchmark. No idea about ATI except that I have always avoided them.
