Windows - taskbar shows doc tabs twice

[gswan]

When hovering over the FlexiPDF taskbar icon in Windows 11, it displays twice as many docs as there are tabs open.
For example, if I have 8 docs open in FlexiPDF, when hovering over the taskbar icon it shows 16 docs to select from.

Thank you for reporting this issue. While I haven't been able to reproduce it on my end, I'd recommend checking if the problem occurs with other applications as well.

Please ensure you're using the latest version of FlexiPDF — you may want to update or reinstall the software if needed.

I have the current version of FlexiPDF installed under Windows 11 Pro.
The problem only occurs with FlexiPDF. I've attached a screenshot to show what it looks like.

Thank you for sharing the screenshot. Please reinstall FlexiPDF and then check.

I reinstalled flexiPDF and it looked fine for a short while and then went back to showing twice as many thumbnails as there are docs open.
Not sure exactly what triggered it.
I had one instance of flexiPDF open with three tabs and then opened an email pdf attachment which started a second instance of flexiPDF. It was then that I noticed the problem again. It would be nice if double-clicking on a PDF or opening an email attachment used the same running instance and opened another tab instead of starting another one.

Are you currently seeing 4 thumbnails or 8 total in your taskbar?

I've forwarded your improvement suggestion about opening files in existing instances.

I have three docs open in FlexiPDF and am seeing six thumbnails.

This issue might be related to your graphics driver. Please:

1. Reinstall the latest graphics driver
2. Update Windows
3. Restart your system and check again

Graphic driver updated just now. Looking better. Will see how it goes over the next few days.
Thanks.

Nope. Didn't fix it.
A few hours later it is back to showing two thumbnails for each document open.
