Hi, While running Opera a window will pop up momentarily out of nowhere & before I can do anything it disappears? I am running Mint Linux 17.3 64 bit, my extensions are as follows:
Adblock Plus
BugMeNot 2
Download Chrome Extension
Facebook Redirect Fixer
FVD Video Downloader
Ghostery
Google Calendar
HTTPS Everywhere
LastPass
Outlook.com Speed Dial
Speed Dial for Gmail
StumbleUpon

Any input is greatly appreciated! Thanks

Does the window show anything, or have a name?
