@leocg I think I have figured the issue out from some quick trial and error.
The issue is only here when I open 2 tabs, but take one and put it next to the other. I have uploaded an image as an example.
When I do this, closing the last tab closes the browser rather than going back to the speed dial page. Do you know how this can be modified to stop that from happening. I need to use multiple browser pages most of the time, and this feature of not closing the browser when the last tab is closed is one of the best.
Thanks again for your time.
