The patch fixes those issues:
- richedit control being hidden when minimizing then restoring application window;
- graphical richedit glitch when application window height is reduced;
- save/load vertical/horizontal splitter size, listview column length;
- window being restored to max size after clicking 'restore' if maximized window was closed previously.
Patch by Edijs Kolesnikovičs and Grégori Macário Harbs.
