Just a little Window nit-pick

I know we're rare, but some of us still use Microsoft Windows.  Those of us who do, often move and resize the windows on our screens.  
So when using 1Password on Windows, is it really necessary for the search field to expand with window size? Along with other options, the entire top of the window is buttons, forcing user to select and move the window with far more precision than necessary.  

I mean sure, I can place my mouse in the 6 pixels above or below the search field.  Or even the 7 pixels between the search and help button.  But a user-friendly interface might give the top dead center of the window a place to grab and move.
