Forum: System Workbench for STM32

header file can not be edited??

I’m using Windows 10
AC6 Version: 1.12.0.201612060912
STM32F469 discovery board

I can edit stm32469i_discovery_lcd.c but can not edit stm32469i_discovery_lcd.h. There is no change when I type anything in stm32469i_discovery_lcd.h. I have another laptop with Windows 8, and it works fine. How can I solve this??

Thanks,
Jimmy
