Selecting text in one of my Notebooks becomes abnormal.
Here is the unselected text:
and here is the partly selected text:
When the text being selected, it should be like this:
What is wrong with this Notebook? my other Notebook is OK!

$\begingroup$ Behavior confirmed in version 7, but I don't know what is causing it. $\endgroup$– Mr.WizardJul 19, 2013 at 1:41

$\begingroup$ If I do a Select All on the downloaded notebook, copy the selection, and paste it into a new notebook, highlighting works as expected in the new notebook. Perhaps you can do the same to recover control over your work. $\endgroup$– m_goldbergJul 19, 2013 at 2:28

$\begingroup$ This question appears to be off-topic because it is too localized; i.e, it applies only to local situation and needs of its poster. $\endgroup$– m_goldbergJul 19, 2013 at 2:29

1$\begingroup$ @m_goldberg You may have noticed that "too localized" is no longer a listed reason for closing. ;-) Anyway, in this case I disagree as it's a curious problem until the solution is revealed, and it could potentially affect anyone who comes across such a Notebook. $\endgroup$– Mr.WizardJul 19, 2013 at 6:18

Your notebook has an option set, ShowSelection -> False, which is causing the problem. Use the Format > Option Inspector... and search for ShowSelection; then click the checkbox to set it to True. Or execute SetOptions[EvaluationNotebook[], ShowSelection -> True] in the notebook.

$\begingroup$ Nice catch! I don't think I've ever seen that option before. $\endgroup$ Jul 19, 2013 at 6:07

$\begingroup$ @Mr.Wizard why it doesn't work for me? The option is false, but I can't make it True. Because it is grey! After I ran "SetOption[EvaluationNotebook[], ShowSelection -> True]", the option is changable. But just for one time. When I look it second time, it becomes false again. $\endgroup$ Jul 19, 2013 at 6:10

1$\begingroup$ @matheorem It worked for me; I used the Option Inspector, chose Selected Notebook in the drop-down menu, and then found the option by typing it in the search field. I reset the option by clicking the "X" to the left of option name. $\endgroup$ Jul 19, 2013 at 6:17

$\begingroup$ @Mr.Wizard "choose Selected Notebook", this step is essential to success. Thank you Mr.Wizard ! $\endgroup$ Jul 20, 2013 at 8:11
