"and as far as I know if you choose to move to the next or latest Windows, you'll have to leave Pic It! behind"
I have to hold my hand up to this Faux Pas. I don't know what I was thinking about when I said this. I have no excuse for this foot in mouth! Of course you can use it in all know Windows after WinXP. I hope I have redeemed myself. what a bad start to the New Year.
But as for using other art software. I personally have tried just about every FREE art programme known to man and woman on the Net. This time I hope you can believe me when I tell you that nothing compares or even comes close to Pic It! for what it can do and the ease of which it does it. It has no limitations.
