why is it taking so long to fix this really annoying bug!!
Because it is not a BUG it is just a poorly designed piece of commercial code. The pop-up is operating as the original pop-up code designer intended it to work [as long as you are seeing the pop-up reducing to the black bar]. The Hornby web team loaded a commercial 'off the shelf' cookie acceptance applet as an emergency. As a short term fill in fix, until such time as it can be replaced with code that is a custom match to the Hornby custom forum software. Good or bad, the majority I think consider it bad, the Hornby forum is a completely custom forum, outsourced to a third party software development company and is not based upon commercial 'off the shelf' forum software. This does make adding changes rather difficult, particularly when done at short notice as in this case. The ComMods do acknowledge however that the replacement of this annoying cookie acceptance pop-up is taking far longer than Hornby admin originally indicated to us that it would take when we originally raised it with them as an issue. Note that the recent 'unable to post URLs and images' issue took the best part of a month to resolve, but it did get resolved in the end. Just be patient.
