David,
The other stuff, however, sounds like a troubling continuation of previous problems. Maybe it is chipset or CPU or board related. On the other hand, changing the memory modules seems to have changed something.
Indeed ---I haven't had *actual* text corruption, at least not since I'm checking with git (what a peace of mind that brings!).
Scary stuff, that. I don't think it likely that the hard disk or its interface is at fault: your symptoms sounded so transitory that they are likely to occur in-memory. Stuff like a bad extension card or a damaged PCB track or terminator on bus line D2 or a solder splash adding unwanted capacity can also lead to such unreliable effects through reflections/delays. Today's computers are annoyingly high frequency devices. At any rate, the symptoms are quite clearly pointing to a hardware problem
I'll keep checking with git for unwanted changes, and for the final run of the book I'll move to my old Mac G5, while I can afford a new machine.
Thank you very much for your kind help ---I'm really less desperate now! Best Axel _______________________________________________ auctex mailing list [email protected] https://lists.gnu.org/mailman/listinfo/auctex
