Thanks Alain.
The scenario is that about 8 days ago I modified the code, and then I have worked on it every day since then. I save, compile and test the code. Each modification I make I flash straight to a pic and test it, so the source code is being saved without fail.
This morning the only code I have available to open , with the same name and in the same directory on the same disk is one from before 8 days ago, and because of the large number of modifications I have been making this week it must have been saved over 100 times.
