Hi ZS,
I don't really use sVB, but it looks like it uses TextBox in its UI designer. It cannot have RichTextBox functionality, they are different things and it is not one of the controls available in sVB UI designer.
To use a RichTextBox, as far as I can see you can use LD extension, maybe others, but not directly from sVB UI designer, unless you get it implement by sVB developer.
This is one of the reasons I try to keep everything compatible with standard SB and use extensions that can interact with standard SB to add features rather than modify the default compiler or SmallBasicLibrary. sVB changes the compiler and basic functions with each version which makes interacting with non standard functionality (e.g. UI designer) in it through extensions impractical. Starndard SB doesn't change, which means writing extensions for it is worth the effort.
What is the difficulty using GraphicsWindow? - I cannot see anything you are doing that cannot be done with GraphicsWindow.
