Hi ​@Tushar K, thank you for posting in the Lucid Community! You are correct - your documents should be opening in a new tab. I can understand how this feature not working properly would impact your workflow, I’m happy to help! To begin, can you please try the below two methods and let me know if they work for you? 

When in the ‘My Documents’ view, select the ‘Open’ button as shown below. 

 Another method is to instead select the three dots at the bottom right. Once the menu opens, select ‘Open’ at the top of the menu. Either of these methods should have your document opening in a new tab. 

A few additional browser troubleshooting tips to try: 

• Make sure you're using the most recent version of your browser.
• Lucid is optimized for Google Chrome. For best performance, we recommend using Chrome.
• Open your document in a different window if your page is running out of memory.
• Open your document in a Chrome incognito window. Doing so disables extensions and clears cache and cookies, which often improves performance. This may also help you identify an extension causing an issue with Lucid performance.

If none of the steps above work for you, please let me know and I would be happy to take a closer look for you! Let me know if you have any additional questions or concerns!

Thanks for getting back to me, I can use the above techniques to open in new tab what I am after is to have my document open in new tab with a single mouse click. This was working until recently. As an additional info, I have another lucid account where the document does open in a new tab on a single mouse click. So this has to do with some setting within lucidchart

Hi ​@Tushar K, thanks for following up! I’m happy to hear that the above workaround is somewhat helpful, but I can understand the continued trouble when attempting to open your document with just a mouse click. I’m unable to reproduce this on my end, and it appears that this may be an account-specific issue.

For that reason, I have converted this thread to a private support ticket and directing this to our support team to get you taken care of. The team works through tickets in the order they are received, and you can expect a quick response to your email associated with your Lucid account. Please refer to that email for further correspondence.
