Enabling this option disables the smart screen updates feature.
•  Show Unprotected NULLs Using Character: If enabled, NULL characters in unprotected fields display using the specified character shown in the Selection Box.
•  Always Use 4-Color Rules when Host Specifies "Default" Color: If enabled, BlueZone overrides the 3270 data stream specification's use of the 2-Color Default color. Select this option if certain screen colors are not displaying as desired.
•  Paint NULLs as Spaces: If enabled, BlueZone paints NULLs in the screen buffer using space characters. This is to aid hooking software that monitors the Win32 ExtTextOut() function.
