Error in Tutorial Adventure

Okay so I am going through the tutorial adventure and get to Page Toolbar, all going well so far. Past this point (see screenshot) the tutorial "stops" and I mean that the black box doesn't progress onto the next "tip/lesson"

Does the Gear Icon not appear to the top left of it when you hover over it?  Can your please follow Steps 1-3 of our Solving Technical Issues checklist (confirm you're using the latest non-beta version of Firefox or Chrome, turn off all extensions, addons, and anti-virus, and clear the cache) to see if one of those components is causing the problem? We can only help if we can recreate the issue, so it is important that each step is followed. If doing that fixes the issue, just let us know. Otherwise, move on to Step 4 to further assist you.

I was using Internet Explorer. I switched to Chrome and it fixed that problem. Ran through the tutorial just to check it was all working. Stopped working again at the Jukebox Stage. Same issue, the black guide box does not appear after one of the steps. Haha, yeah sure I will run through those steps when I re-continue the tutorial. Its a good tutorial ! Chrome is newly installed, last week, the only extension is Google Docs and my security app.

Yeah we do not support Internet Explorer so that was likely the issue. We currently support Chrome and Firefox. Are you still stuck at the jukebox stage?

While I ran into similar problems, disabling my Ad Block Plus seemed to take care of the issue for me. I'm thinking that somehow ABP interacts with Roll20's little bubbles at random times and causes the error, but I can't be 100% certain since it seems everyone else freezes at around the same time (according to the posts I've read). That being said, there is another error which I couldn't resolve (which I'm posting here rather than creating a new thread because it's along the same lines as this one). In the Deck section, the tutorial has you show the deck and then manipulate it a bit, but the deck is placed at least partially (if not fully) behind the tutorial menu, making it very difficult (or downright impossible) to continue. I disabled my two add-ons, cleared my cache, and nothing changed. I was able to work around it using a few tricks (since my deck appeared only half covered I was able to use Deal and then dragged the card from there onto the VTT), but I couldn't follow the tutorial as-written. I've seen other similar posts in this forum, but the topics have all been closed. I'm using: Browser: Firefox 41.0.2 OS: Windows 10 Home Antivirus: Webroot (though I disabled it to test and still came up with the same issue). I'd include a screenshot, but I don't know how I'd get back into the tutorial at this point. If anyone knows, I'd be more than happy to provide one.

What screen resolution do you have Tyr H ? 

It's 1366x768. I suppose I should've thought of that... I'm guess the tutorial is built around a different size?

Yeah I believe it was built around 1920x1080. We are working on scaling it to work with all common resolutions. Lower resolution might be causing  some of the text boxes to overlap which is likely what you are running into.
