You probably know this already, but when running the Learn/Basic Curriculum programs the text is overlaying as you resize text DAT in lesson /TDFundamentals_107_readingAndUsingTheTextport similar to attached screenshot. Script still runs ok but hard to read the code.
Thanks for the report. This has been fixed now for the next release. T
The issue was specifically when word wrap was enabled on formatted text. If you turn the word wrap off on the Common page of the parameter box the text should be more readable.
