We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello Reno,

thanks for your suggestion but my drivers are not that old and if the software has been crashing for years in versions 4.7 to 4.12 under different drivers, I am not going to risk anything by forcing bleeding edge drivers unless it is written somewhere that a specific driver version solves a specific problem. 

From my point of view, an issue is the apparent randomness of the crash or the dependency to the system which may prevent the debugging. I saved model and cfile that crashed prepost 4.11 and 4.7 yesterday on a machine, but it works fine on another machine today. Typical.

It is pointless to send I guess, suggesting that these crashes will not be solved based on the cfile only and that some other form of information is needed to improve the quality of the software. The developers may say that it is due to specificities of the system but that is the name of the game for all software and many software packages are stable. It's too bad because prepost really does a lot of things.

I'll stop here. 

Thanks

Philippe
