If you have high display resolution, the text in Lotus Notes can be too small. Lotus Notes does not allow you to change the size of the font from the graphical menu.
To increase the font size, edit the c:\lotus\notes\notes.ini file, or wherever this file is placed on your computer.
Add the following line of code on a new line:
Display_font_adjustment=15
Where the 15 can be changed to any other integer number. In the above example the font size will be increased by 15 points.
Now you can start Notes and the font will be bigger, if it isn't the PC reboot will be necessary.
