We are troubleshooting an issue impacting community login, and it may be intermittently unavailable. Sorry for any inconvenience.
I could not find a switch or preference to disable this. I suspect that the trigger is some javascript function that you maybe able to disable through customization.
@Phillip1.. there are couple of javascript functions related to WVSPopup and mouse over in \netmarkets\javascript\util\windchill-all.js, but I won't recommend modifying the javascript file directly.
Thanks,
