Cheat Engine

[Stacktrace]

I'm having a big problem with creating a trainer (CT).

Basically, you know when you have a button ready and you go to the events tab to add an OnClick function? Yeah, I've done that.. I've added this into it:

function CEButton1Click(sender)
showMessage("Test")
end

once I go back to "Restore and show" the trainer all the changes I've done in the events tab just gets removed, I've never had this issue before.. I'm using Cheat Engine 6.3 (Obviously 6.4 wouldn't fix it, just saying..)
This is a big pain in the ass because I've worked hard on getting all the buttons the perfect size, many buttons close together all same size, height, nice looking clean trainer, but I cannot add any scripts!!

Before clicking restore and show you must close the designer first (so it gets saved), else it will (as it says) restore it to the last saved state
