Hi Spud,
sorry to be mysterious.
I meant: When you are writing a post, after a couple of minutes mark the whole stuff (hold left click down on your mouse and "fly" over the whole stuff; it´s then bluish/blue "marked") you have written, right click your mouse, choose in the dialog-menue "copy". That´s it for the first step.
Do this regularly for the whole stuff!
So you ever have a complete copy of your post you can paste back (in your posting-window(THIS one where I´m writing now and where you writing your post) by:
cursor in THIS window, right click your mouse, choose "paste"(drop down) and everything is there again
That´s all.
Hope this is clear enough!
Cheers Rainer
