Tools, Tagging Tools, Search & Replace no Replace

Another thing, unfortunately this doesn't happen all the time so I can't fully/consistently replicate it. Occasionally I will split the screen to have a web browser on one side and MusicBee on the other which is how I first noticed this.
With 4 tabs open, while on any tab, if I hit the restore/maximize button (you know, in the top right corner) to reduce the window size and then hit the button again to restore to max screen, it will stay on the same tab.
With 5 tabs open and doing this, a new empty tab will open sometimes at the end and MusicBee will switch to this empty tab.
With 6 tabs open and from one of the 5 previous tabs, MusicBee will sometimes switch to the 6th tab.
With 7 tabs and on any tab other than the 6th, it will sometimes switch to the 6th.
