In July 2003, Rose and Clarke started working on a Windows version with another software programmer, but internal differences broke them up and they were forced to scrap the work already done. Later, Rose persuaded Ed Voas (who was then a friend of Rose and had 10 years of software programming experience at Apple Computer, and would later become the third member of Konfabulator's core development team) to develop a Windows version for them. Initially he declined, but later he created a working prototype and presented it to the Konfabulator development team within two days.
