"Trust access to the VBA project model" is something I instinctively click on right after "Enable all macros", simply because I don't have time to workout whether or not it will break the code I would like to run.
This is naughty - I should know what I'm doing and the implications. Assuming I've enabled all macros already, what extra features/dangers are exposed to me when I open the Pandora's Box of trusting access to the VBA project model?
This line of code runs without trusting access:
VBAProject.Sheet1.Calculate
Please would you post some code that requires trusted access?
