V1.0.1.0: disable "Select file" after programm start

see screenshot, directly after startup the button "Select file" is clickable (and works) but the checkbox "Use loadable modules" is false.
User can select a basefirmware without enabling the loadable modules. Afterwards he selects an nxo file and configures the warmstart messages and wonders why the firmware does not start.
Disable the "Select file" button on startup, so user is forced to set the checkbox.
Enabling and disabling the checkbox disables the button. This behaviour is correct.
