In Windows installations with non-latin languages it can happen that the text in the 4DScript editor is displayed either blur or simply out of focus.
Sometimes it helps to switch fonts (from non true-type to true-type or vice versa). If that does not help you can also disable the coloring of the text by pressing CTRL+O. This will switch off the coloring displaying the text in black only.
Text in editor is blur / not displaying correctly
