From doc/readme.version_1.7.5:
Regarding bug fixes, foremost of all, some of FLTK widgets have
been updated, which has caused some changes in mysqlgui source code.
Some users have reported problems with X 4.0.* when using some
widgets. This has been fixed. Beside that, column resizing in
spreadsheet now works. Also, editing (in order to scroll text) and
zooming is not automatic, but you should press F2 or Ctrl+E in order
to scroll a cell or to zoom it. This has resulted in faster scrolling
of the spreadsheet. Some aesthetic changes have been implemented
in some widgets. Also, process dialogue display is now more readable.
