I would be interested to know if other people:
- can recreate the problem (please specify the browser and OS)
- have had similar experiences with any websites
- had any ideas what might be causing problem

One thing that I thought might be a possibility is that some web element, when being resized, would cause a problem. But that's speculation, I don't have evidence for that.

There is nothing about this site to cause this and furthermore it sounds like a browser bug

It might only have anything to do with IE. Not many use it anymore that I know of. I use Brave, that has many funky things because of its immaturity, but zooming is smooth..

I've been having a problem that's been annoying me for some time. However, the problem was very irregular so it was hard to reproduce the problem consistently. Now I believe I've finally got it more or less described.

- I use Internet Explorer 11 on Windows 7.
- When I zoom in on forum pages, sometimes the scrolling gets stuck, that is WheelUp/WheelDown (mouse wheel), and up/down arrow keys.
- This seems to happen on certain specific percentages: 120% / 160% / 175% / 230%, but it doesn't *always* happen at those percentages.
- It appears that the window needs to be maximised for this to occur.
- It gets stuck when you increase the zoom e.g. from 115% to 120%, but it does not get stuck when you decrease the zoom e.g. from 125% to 120%.
- It happens on thread pages e.g. this page.

Note:
- You can do View, Toolbars, Status bar, to see what the zoom is.
- You can do Ctrl+WheelUp/WheelDown, to increase/decrease the zoom by 5%.

Thank you for reading.
