Why do they have this in the list of examples of 'run-on sentences':
> Bad: To access your programs click the Start button.
> Improvement: To access your programs, click Start.
Sure, the improved version has added a comma, but the initial version is not a 'run-on sentence'; it does not contain 'two or more complete ideas that are joined without punctuation'. The comma here is completely intonational; it would not be needed if the word order was different, as in 'Click Start to access your programs'.
