WebHelp Output Menu Locks Up

Hello,

I use Robohelp 2017 and Chrome.

Do you know why my WebHelp Output Menu freezes up in Chrome and I keep having to hit the refresh button to get it to work again? It seems to be ok in IE.

Here is a detailed example:

1. I click on "Acro" to view the Acronyms page.

2. I click on the Acronyms page and scroll through the page to read it.

3. When I click on "Basic Satcom Info" on the menu, it won't expand because it's stuck or locked up.

4. I have to hit the refresh button to get the menu to expand.

5. Now the menu will expand, until I click in the information pane to read the material. The menu will lock up again and I will have to hit refresh to expand it for the next item.

Here is how I generate the presentation.

Any ideas? My customer doesn't like having to refresh all the time.

Thanks
