Hi Martin,

> But whilst on this kind of subject, is there an autosave feature ?

No, not currently. Autosave can tend to be rather intrusive once you get to a fair sized model.

If your computer tends to blue screen when coming out of sleep mode, probably you should go to Control Panel > Power Options, and set it so that it does not ever go into sleep mode, you can set it to "System standby: Never" to do that I think.

Also the blue screen is probably caused by one particular buggy driver misbehaving - if you configure your system to create crash dumps on blue screens (Control panel > System > Advanced > "Startup and Recovery" settings > Write debugging information set to "Small memory dump") that could make it possible to look at the crash dump and maybe get a clue which particular driver is the culprit, then you could disable that particular one or try to update it.
