From a maximized state, you have to hit the "Restore Down" button on the title bar to resize. Then you can grab the edges to resize. If you can't grab an edge, move Sigil a bit (after restoring down) by dragging the toolbar so one of it's edges becomes available to grab.
It seems to be maximizing just a titch beyond the actual screen-size, but other than that, can't get it to misbehave on Windows or Linux.
