Sorry but given the trouble I've seen with incredimail, I can write I consider it malicious and troublesome for users.
I'd dump that.
I have Vista and have been using incredimail and family tree maker for at least 4 years on the same computer. All of a sudden while opening an email I get the message "a problem caused the program stop working correctly. windows will close the program and notify if a solution is available." I would have to open the program again and if i would click on an email I again got the message. When I have family tree maker and working with it I keep getting this same message. I have updated incredimail, uninstalled and reinstalled it and it still will not work. Same with family tree maker. HELP
