The program used to tell me whenever I tried to add a new color that was already part of the current pattern, and while I don't remember changing any settings, I'm wondering if there is any way to get that function back.
I'm only answering this one post (the other is identical). You don't say what version of PCStitch you have and have posted under both 10 and 9 so I can't tell.
You must have accidentally clicked on the option not to show the window again. I do not know how to get that back. I suggest you contact Mark. When you find out, please post the answer.
It's possible that a re-install OVER the existing install will get that back. You should not have to re-register the product.
