For some reason, I can't move or size my components. PLease help. I tried to create another page, I was able to move components and change their size. So I started redoing everything on a new app but at some point, the same issue recurred
Hey @Long_Lai, welcome to the Community! 
Thanks for reporting this. Can you answer a few questions to help me investigate?
- Which browser are you using? Does the issue occur in multiple browsers?
- Are you on Retool Cloud or a self hosted instance? If self hosted, which version?
- Do you see any errors in the browser console when the issue occurs?
If you can share a screenshot or a short Loom video, that would be super helpful. Thank you!
If live debugging help would be useful, we have an upcoming Office Hours session today Sept 23 at 2pm EST where you can get help directly from the Retool team and other developers. We host these Office Hours twice a week! 
Hello there @Long_Lai, just checking in to see how you’re doing and if you had a chance to take a look at the questions I shared above. Do you still need help with this? 
Hi,
It seems the UI froze because one of my queries got triggered infinitely and broke the page. After deactivate the query, every thing worked fine.
@Long_Lai Ah, that’s great to hear you found the root cause! If you have any other questions, feel free to start a new topic. I’m here to help
