@sirbots My project is not large i just got into this site, and the block I am using as a reference is Say (Hello)
So it should just say hello but instead I have to refresh the whole page as you descfribed.

Whenever I click on a block in the palette, the flag stops working, and all scripts will not run. I have to refresh the page.

Steps to recreate:
Make a new project
Click on a block in the palette

Please help, I’m new here and this platform looks promising, but I have a habit of previewing the blocks!
