Why does RoboHelp HTML v11.0.1.235 crashes when inserting a script?

Question

I inserted the following script
"<noscript>
<!--Javascript is not enabled-->
</noscript>".
I used the menu options Insert > HTML > Advanced > Script. Unfortunately, RoboHelp places this tag inside the "<script>" "</script>" tags which causes errors. I was in the procces of moving the tags when RoboHelp froze. RoboHelp (HTML) v11.0.1.235 was installed on my system last week. There is an Add-on to Microsoft Visual Studio (v4.5.50938) where all the files are kept in Source Control. The contents of the problem details are below:

Answer 1

I have to update all HTML files with the noscript tag for browsers that users may have that does not support Javascript. My predecessor entered the HTML coding (script) incorrectly. by entering the text "Javascript is not enabled" at the top of each topic page in the online manual. Unfortunately, users accessing the WebHelp manual discovered that when "full text" or "word" search was performed the text appeared in the search results as part of the title of the page. When looking for assistance on how to correctly insert this tag I came across the RoboHelp Reference for entering this script. Note: I was using RoboHelp v9

This is how the above is entered in a topic: (HTML view)
This is how the script/tags should appear.
The system does not freeze up every time. I can work on a few topics (maybe 5 or 6) then it will freeze. I am not sure if the problem has anything to do with inserting a script but this is the only time it freezes. I use RoboHelp on a daily basis and is in it all day long for I am a Technical Writer assigned to preparing and updating online manuals. If I am creating a new topic or updating content on a topic (Design view) the system doesn't freeze up.
