Hello,
In my OnProjectLoad() function, I added the following line:
Edit.SysVar(VAR_BREAK_AT_THIS_SYMBOL, "reset_vector");
But when opening the project, I can see in Ozone Console this line instead of my one (and the previous lines are the ones from my function so I'm sure to execute the correct function):

Edit.SysVar (VAR_BREAK_AT_THIS_SYMBOL, main);
So my breakpoint is still set to "main" in "System Variables window" and at execution.
The only solution I have found is to set manually "reset_vector" in "System Variables window" but it is not convenient for my purpose.
Any idea?
Thanks.
