If you run Magic Draw on a system a screen high resolution, the fonts in Magic Draw and even in the E2E Actions Script Edit may be very small.
I had this issue when working on my laptop having not a very big screen, but a high resolution. I tried several settings, but the only one that really did help for me was the following.
With a right-click on the shortcut starting Magic Draw I’ve open the properties dialog. There I was choosing the “Compatibility” tab and have checked the “Override high DPI scaling behavior” and did choose “Scaling performed by System”.
After restarting Magic Draw with this setting, I’ve got well readable fonts in Magic Draw and E2E Action Script as well.
This setting helps for the E2E Analyzer and some other applications as well.
