We found in several notes.ini files bad formatted lines. Most of those lines are (part) of a date/time like “1-2007 10:40:12”. But some lines have a shorter date/time and others have a longer date/time.
We found these lines both in our 6.5.5 and 7.0.2 clients.
This comes from saving garbage to an environment variable using code. I incurred a similar problem where I was saving a value with @SetEnvironment using the contents of a field. I do not remember whether or not the field was RT, but it contained line breaks and other nonsense. As best I recall, this effectively caused everything below that point in the INI to be ignored.
