I am having the oddest issue. When i try to select a snippet.....it disappears. Not sure what kind of info you would need for this. I am on google chrome.
it does not disappear like it does here. But when i select the code, ether by mouse drag, right click select all, or CTRL-A, The code does not stay selected.
Do you have any text selection plugins installed for Chrome? Also, are you updated to the latest version? I don't have any trouble with Chrome myself. I'll update the Codemirror we have here to see if that helps.
What if you click into the box and press control+A to select all?
