Every time this projects starts some errors show up. I pictured the log of one below. ![startuplog](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/6/862f59789a70c5855f0b2ba6a0dad132f2edd199.png) But I don’t know what this is coming from, or what is attempting to access it? How do I sniff this out? Thank you in advance! ---

It is a `system.tag.write.....()` function call in a script. Look in your startup events. Look in all of the scripts in the windows that auto-start in that project. ---

@pturmel that was enough to point me in the right direction for this and another question I posted. It only opens to two windows. But there were many other windows set to open on startup. I disabled them all but the two needed. Thank you!
