B4J Question [ABMaterial] Switching page requires clicking menu option two times

I use the demo project inside this post

[ABMaterial] For Dummies (beginner lessons)

ABMaterial For Dummies This has often been asked for - so it is high time to produce a simple set of guidelines to help get you across the short learning curve. Take your time and see what you have been missing in simplifying web app creation with ABMaterial! IMPORTANT UPDATE...

The only thing I changed was to comment out the following line of code which caused "unknown method" and which should be removed based on the accompanying comment.

    ' turn this mis-guided feature OFF - doesn't play well with others....  will be removed in future updates...
    ABM.EnablePassiveEventListeners=False

I've noticed that to switch to a different page, I need to click the corresponding menu option two times, not a single double-click. Below are logs shown when I tried to goto About page from ABMPageTemplate. It should be done in a single click; could someone kindly show me what was wrong and how to fix it?

Further testing results on Windows 10 64-bit:
1. Firefox and Edge works
2. Chrome and Opera still have this problem.

Test results on phones:
1. Google pixel 4A: Chrome failed while the other 3 worked.
2. Samsung Galaxy A11: Chrome and Edge failed while the other 2 worked.

Has anyone have similar experience?

After the first click, the logs indicates that it tried to load the current page (ABMPageTemplate) by mistake for unknown reason, if I understand it correctly.

The problem is in the NavigateToPage and NavigateToPageNewTab methods. Remove the ws.close statements in both methods. This is probably something that has changed since 2018 (or with jServer 4).

Tip: I updated the ABM Mini project to the latest version of ABM: https://www.b4x.com/android/forum/t...-absolute-beginners-update-2022-09-08.117237/

There were hours of self-hate before I realized that clicking twice got me to where I wanted to be.

I am new and thought I had latest ABMExtras.zip, but needed to comment out those "ALSO NEW 4.00" lines.

BTW, @alwaysbusy, this update is not applied into a new ABMServer.b4xlib v.1.07
