The popup blocks any input to Media Center. That's why the close buttons are on the popup.
This is whilst not in popup mode
I click on a large field edit type, and it expands. The attached image therefore shows what I see when editing a large tag.
In order to 'close' this large edit, I have to do one of the following:
* Scroll and click into another field. (Can't just click into another field, as it fills nearly all the available space)
* Use the tab key to move to the next field.
The popup mode could do with tweaking too, now that I look at it (not something I normally use).
When this is closed, we come straight back to the open large edit as per my screenshot.
I'd (personally- others may have different opionions) put it back to the contracted state.
Basically, a clicky button to the left of
Edit in Popup in my first image would to me at least give a nice trigger and visual cue to deliberately close / save the edited tag. I'd likely avoid the confirmation dialog you see when using the popup, would want to double think that though.
Done. Thanks
