Andrew, thank you for your quick reply, as usual
Could be screensaver's fault, yes ?
I better believe that somehow the windows taskbar was keeping too much links to previous tasks and first displayed the first loaded QCAD image, even if I closed it long before. I closed it again.
Later, after my search for the QCAD version, the last active task appeared back in the taskbar and when I selected it, my project was there with its last content.
Still, what I don't understand (and for sure there will be many things I shall never understand, be it in IT or in real life like women - generally
)) - children smiles or building balance - Pisa tower - or a stair calculation)... is why the file was still displayed in its folder as saved at 18:14.
Happily, everything is ok !
But I hope I'm not too late, Andrew, to wish you (again ?) the best for 2010 and as it's never too early to begin with the good things, I wish you the best until the end of 2010
"bonne fin d'année" !
... including hoping for some way to copy one complete layer - at the layer level - globally from one project (file) to another one.
