Basic Themes in Windows 7 can cause ghosting of dialogs in IRRICAD V14
If your outlet or sprayline dialog remains on the screen for each new sprinkler or outlet connector selected check which theme is being used.
To do so go to Control Panel | Personalization.
Change the theme from "Basic and High Contrast Themes" to an "Aero" or "Installed" Theme.
Installing the latest Version 14 patch will correct this issue.
