Los cuadros de diálogo en los programas de Dlubal Software están optimizados para una escala de visualización del 100% en la configuración del panel de control del propio equipo. The problem can be corrected if you change the scale settings in the Control Panel to "Recommended" (see Image 01) or/and a higher resolution.
Another option is to deactivate the high DPI scaling values. To do this, open the Properties of the program by right-clicking on the program icon. Under the Compatibility tab, check the box for "Override high DPI scaling behavior. Scaling performed by:" and select "System" from the drop-down box. Then accept the change, confirm changes, and restart RFEM if it is left open.
