Many on here use window cleaning pro fantastic features, updates galore and support within seconds. Many jumped in and purchased it. I use George and it does every thing I need. But it's a bit boring you email for support and you get a reply you ask for new features and Paul does them. If your system crashes even on a Sunday you get a reply, were is the fun in that At least with window cleaner pro you get your money's worth, you email and email ring email see a lot more fun Roy
