Adding a new swim lane freezes my document

​@steven.rawley this is a known issue with a workaround. Please see this thread: 

Hi ​@steven.rawley, thank you for posting in the Lucid community! Thank you ​@aparrish for providing that resource - it does look like another user was running into something similar. 

Testing on my end, I haven’t been able to reproduce this quite yet. 

Would you mind trying the following steps first to see if performance improves and you’re able to add a swimlane? Sometimes account performance issues can be related to internet security/speed or browser issues. These steps will help us eliminate that possibility.

• Opening your board in a private or incognito window to help us narrow down the potential cause. For help with opening an incognito window, please see this community post.
• Connecting to a different network or disconnecting from your VPN (if applicable).

If those don’t resolve the problem, can you please send the following information so I can take a closer look?

• A screenshot of the issue.
• A screenshot of the associated Javascript Console output after reproducing the issue. You can open your Javascript Console by pressing Ctrl+Shift+J (if your computer is a Windows/Linux) OR Cmd+Opt+J (if your computer is a Mac).

Thanks in advance for your help and patience!
