Classicladder not saved

Hi,

Today I've started my first experiment with Classicladder.
I've added the input and output signals to the HAL file
I can see that the input signal from the 7i77 is shown in the "Bit Status" of Classicladder
I also can activate the outputs on the 7i77 by selecting the checkbox in the "Bit Status".
But when I write a simple program, it does not work.
I've seen that when I save the program, en reopen it again... it is empty.

what am I doing wrong?

If I add a section, this is saved when I reopen Classicladder.
But the rest is gone...

Ok, I found the problem...
You first have to click OK before saving

Hi BigJohnT

This was indeed the problem.
Tx!!!
