Compatibility problem

I have an old model built on version 4.01 and I try to open it using version 4.32. It crashes my system and a core dump blue screen is displayed. I think that it is important to let user to reuse their old models. I have attached the model to this message and I hope that somebody can figure out the problem and fix it. WARNING: the attached model may crash your system if you are using version 4.32 but it works normally in version 4.01

Bill,

I don't see your model attached.

Sorry. I do not aware that I have to zip it first.

Sorry Bill,

I opened your model in V4.32 answerded the question to update it with "no" and everything worked fine for me. I saved the model again in 4.32. You find that attached and can check if it works now, but something seems to be wrong on your system.

Hi Ralf,
Thank you very much. Most of the PCs in our lab have the same configuration and they have the same problem with the model. I've followed the way you open the model in some other machines and I can get the same result as yours. You are right. The problem must be related to our system and I'll try to figure it out. Again, thank you for your help.

Best Regards,
Bill

I have the following findings on the compatibility problem and I want to share it here:

1. The problem is found in a group of PCs having the same hardware and software configuration.
2. The problem can be removed by simply selecting the "High Compatibility" option in the Graphics Configurator. The original setting is "High Quality" by default.
3. Latest version of driver is then downloaded from the graphics chipset manufacturer's web site and installed in the system. To test whether the problem is still exist, the setting is switched back to "High Quality" mode. The result is no core dump problem. However, I find that the "ALT click and drag" method cannot be used to connect any object even if I start a new model. This problem can also be removed by selecting the "High Compatibility" option in the Graphics Configurator.
4. The PCs' model are HP Compaq dx7300. The graphics chipset is the Intel Q965/Q963 Express Chipset Family. The old driver is version 6.14.10.4642 and the new driver is 6.14.10.4964. For reference, I have another PC that do no show any of the above problem. The model is HP Compaq dc7600. The graphics chipset is the Intel 82945G Express Chipset Family.

I hope the above information is useful.
