it happens when i downloaded you ladder from:
http://cq.cx/ladder-forum.pl?a...;parent=7299&tt=1526869620
called "Pwm_Bright_Pot.ld"
it is selected 328p mcu, so i change to pic 16f877a in the same ladder then i press MCU paramters then ldmicro 4.4.0.2 closes, but if i do the same with 4.4.0.0 it gives me an error message wich is ok to show it, but in 4.4.0.2 instead of showing the error message it closes
