The screenshot button no longer works for me as of the update that added the sound button. (By the way, I really appreciate the sound button!) Every time I click screenshot, the deck builder button appears over the screenshot button for a split second, and the follow error message is output to the console:

Unchecked runtime.lastError while running downloads.download: Invalid filename

at KCScreenshot.saveDownload (chrome-extension://hkgmldnainaglpjngpajnnjfhpdjkohh/library/objects.js:8:2186)

at KCScreenshot.output (chrome-extension://hkgmldnainaglpjngpajnnjfhpdjkohh/library/objects.js:8:2009)

at Object.callback (chrome-extension://hkgmldnainaglpjngpajnnjfhpdjkohh/library/objects.js:8:1901)

I asked someone else if they were having the same issue, and they said they were occasionally able to take screenshots, but the button would randomly fail on them.
