Assistance needed to stop blinking thumb in activex scroll bar

[Voyager]

Hi experts,
I’m using a dark themed form since we cannot change the colour of default scroll bars I have taken activex scroll bar and was able to change the colour. But after I finish scrolling the thumb starts blinking which looks awkward.All I needed is to stop that blinking. I tried setting tab stop to false but it doesn’t work.

I note your question has yet to receive a reply, hence I am bumping it up the list hoping that it will get a second look!

Blinking in that context implies that Windows is saying something needs attention. Find out what needs attention and address that issue. The blinking should stop.
