Character sheet disappears when dragging spells from PHB

Why does this happen?  I can't add anything to character sheet because when I click on anything else, the sheet disappears.  I can't drag the spell over to it's place on the character sheet.  How do you keep the character sheet open?

I'm assuming this is the official 5e OGL sheet. Are you popping the sheet out into it's own browser window? Drag and drop doesn't work with sheets that are in separate windows - they need to be open on the tabletop. If it is happening with sheets open on the tabletop, then I'd suggest trying the troubleshooting steps found here:&nbsp; <a href="https://app.roll20.net/forum/post/3/read-first-submitting-bug-reports-and-faq#post-3" rel="nofollow">https://app.roll20.net/forum/post/3/read-first-submitting-bug-reports-and-faq#post-3</a> &nbsp;

If popping out is indeed the problem, you can control this behavior here on the settings tab on the right hand side of the sidebar while you are logged into your game.

Popouts were the problem.&nbsp; I usually don't use them but must have enabled them at some point.&nbsp; They are now turned off.&nbsp; Thank you for your help.
