Filter Box has a misleading auto selection

If you enter everything in the Filter Box and close Mp3tg and he reopen it- the content of Filter Box is selected. This suggests that the user has the focus in it- and yet the focus is... nowhere

1] I suggests removing that auto-selection as it is misleading
2] I propose adding the ability to be able to set up where the focus should be after opening of Mp3tag. I personally would like to have it in the Filter Box [and if it would be turned off, then my focus should be nowhere]
3] I would like to kindly recall my previous suggestion conserning selections in teh Filter Box:
