Is there any way to prevent the code from running on the EV3 as soon as it downloads? I sometimes see this happening and sometimes not.

This could be dangerous for the equipment as it could cause it to roll right off the table.

I have started coding a “pause until enter” structure on every program, but wondering if I’m missing something because sometimes the program runs on download and sometimes it does not.

Thanks for your help!

You need to pause at the very beginning. In firmware 1.10E, LEGO developers implemented a way for the EV3 to automatically perform some file manipulations when loading a program file. This can’t be changed. I can do this when loading via Bluetooth in the BrickCode fork, but it would be a poor implementation, as different loading methods would work differently. This could confuse the user.
