Embedded List in WebX not scrollable

[Ali80]

Hi all!!

Does anybody know the reason why an operator from a remote WebX Client can't control the navigation bar on the right side from an embedded list (up/down). If he try to shift the full event list (=embedded list) with the navigation buttons up/down then nothing happens. The list is like frozen. On the other side if I for myself try to move the embedded list down from the internet explorer 11 from my PC then it works. Why it works on my PC and not on the PC from the remote operator ??

I would be very glad if anyone had an idea what can be the reason. Thanks!!

Best regards

Alois

I have never had this happen, but I would try deleting the ActiveX and reinstalling it on the Remote Operator's PC.

When you say 'navigation buttons', you mean using the scroll bar right?

So clicking the up/down at the ends of the scroll bar don't work, how about trying to 'slide' the scroll bar?

What OS and browser are they using?

Are they using the browser on their local computer, or are they connecting via a Citrix/Remote Desktop service?

I have seen this issue when using Citrix, and it was a weird Citrix 'thing'.  Logging out and back into a new session fixed it each time it happened.

As @geoffpatton has mentioned, I would try to remove and reinstall the ActiveX control.

I would also have the user try a different computer, to see if it's profile based, or just computer based.

Did you solve this problem?  If Geoff's answer got you there, you could mark it as the solution, or provide additional detail as to how you resolved the issue and mark that as the solution.

We are having this after the latest client update in Citrix. Doing a clean install of the plugin doesn't change anything - but there's still no scrolling in the meter list. Anyone have any luck?

There were a couple of Microsoft Windows Updates that broke the scroll bar functionality within Embedded Lists.

This issue was reproducible across various Geo SCADA builds and affects WebX in Edge using IE mode.

The Geo SCADA Knowledge Base article for Microsoft Update Testing identified this as a problem. (https://community.se.com/t5/Geo-SCADA-Knowledge-Base/Microsoft-Update-Testing/ba-p/279120)

From we suspected the following Windows Updates to be the root cause:

KB5033371, KB5033372.

Uninstalling the Windows patch KB5033372 (Cumulative/Security Update for Windows 10) made the scrollbars work again.

The later January 9 2024 Windows 10 Update – KB5034122 states the following: "This update addresses an issue that affects the ActiveX scroll bar. It does not work in IE mode."

Also resolved for Windows 11:

23H2 and 22H2

TL;DR; Microsoft updates in December broke it, get January updates to fix it again.

It's good that Microsoft are continuing to support ActiveX, but it won't be used in Geo SCADA for much longer!

Thanks for the update. We will try this fix. We are on server 2016 but it seems to be the same cause.
