Painter 12 Airbrush question

[Mbabane]

I have Painter 12 running on Windows 7 and Wacom Intuous3 tablet with latest driver 634.3. For some reason I can no longer get my airbrush to paint an angled cone - only a round spray. I'm certain this is probably a setting but for the life of me cannot find how to fix it! Any suggestions would be appreciated

Problem resolved. For those who may experience same - installed new driver without removing old one first!
