I think there is a bug in how Studio 2019 behaves if you right-click a word marked as misspelled when Center Active Row is enabled in Options > Editor, and the word you right-click is NOT currently centered. To reproduce: Have Center Active Row enabled. Open a document for translation. Write some text, some of which is misspelled. Make sure the segment is NOT centered (scroll the document with the mouse to place the segment at the top or bottom of the screen). Right-click a word marked as misspelled. On my PC, this causes the segment with the misspelled word to "jump" to the center position, and the general right-click menu to show, not the spell-check right-click menu.
In the first screendump you see a misspelled word in a segment which is not centered. In the second screendump, I have just right-clicked the misspelled word. This has caused the segment with the misspelled word to "jump" to the center position (in this case, to jump from the upper part of the editor (the green rectangle) to the center (the red rectangle)). At the same time, the right-click menu that opens is not the spell-check right-click menu as expected, but the general right-click menu.
Expected behavior: The spell-check right-click menu should open, and the segment should not jump to center position in this case, but only when you confirm segments.
