Question

CP published as Flash 9 fails in Chrome/IE8 64bit?

Had an email exchange with the boss today. He wanted to review my work, so I sent him the link and got an email back a few minutes later that said: "The UI flashes on the screen for a moment and then i get a blank screen".

He's using IE8 on a 64bit OS. I launched the course in Chrome a number of times and noted the same thing. Here is what I told him, and I'd welcome your feedback as to whether or not you have encountered this recently:

Hmmm… I will look on the forums. This seems like a recent artifact. Cant help but notice you mentioned seeing the UI for an instant before the screen goes black (or white, in my case in Chrome). When the course loads and runs properly on my IE, the UI flashes onto the screen at first, but is instantly replaced by the standard “Loading…” screen (the UI has disappeared and is replace by gray background at this point). After a few seconds of “Loading…” it all comes back and plays properly.

In Chrome and IE 8 64bit – it looks like whatever is going on during the “Loading…” process is crapping out and leaving us with much unimpressive blankness for our efforts.

I’ll see if the propellerheads on the Captivate forums have encountered this.

Okay, propellerheads -- is this a browser security issue? Javascript unpleasantness? Chrome's too cool for my Flash-based elearning?? 😉

More users/reviewers are reporting the same "Black-screen" issues on 32-bit OS/browser platforms. The offending course is published as a Flash 9 captivate piece that itself has several a few SWF segments embedded in it (also published as Flash 9) along with a few F4V segments as well. One of the embedded SWF segments itslef has an embedded F4V segment, fwiw.

Another developer/troubleshooter is assessing the differences between his machines that play the content, and those that dish up black screens. He hinted a little while ago that the Flash Player and/or Active X Player versions between the playing vs non-playing machines might be different and he is trying to document the versions and to incrementally adjust versions of the Flash and Active X players to see if some tweaks will cause the courseware to start playing.

I will post any results (positive or negative) that we get asap.

Hello Mike,

  1. What is the Flash Player version you are using?
  2. Do you have any Text Animations in the project? If so, can you remove them and check whether it plays in Chrome?
  3. You mentioned that it plays fine in IE and Firefox, are they in the same machine?

Thanks,

Vish

Hi Vish. Excellent suggestion. Indeed we did have several slides with animated text in them (text/images with EFFECTS applied to them on the effects tab). I've gone through the piece and pulled out all animations and republished. Still no success on several of our machines now.

We have published the course is both Flash 9 and Flash 10, and have viewed the content with Flash 10. I'm not sure if the machines have Flash 9 or Flash 10 installed players yet -- we have another technician going through a series of machiens right now collecting the configurations.

Interesting to note -- When courses were published to Flash 9 and viewed with the Flash 10 player, animations and video continue to play even after the learner advances the course to the next slide (animation/video should stop, but the audio continues). I posted another thread about this issue the other day and have seen several other threads about this as well. While testing the "Black Screen of Woe" issue, I discovered that publishing the course as Flash 10 and viewing on a Flash 10 player solves the probelm of AV audio continuing to play when the learner advances (fwiw).

I am now porting the "troubleshome" course piece-by-piece into another test course that is currently publishing and viewable on the troublesome machines. Hoping to hone-in on the offending bit of code/content by publishing and testing iterations of this process.

Thanks for the suggestion.

Mike

Excellent bit if information -- thanks as always.

Interestingly enough, though, my boss has tested it on a number of other machines (desktops/laptops) with 32-bit OS/browser configuration all with the same result on HIS machines. The common thread among the machines is a recent Adobe Air update. I think he did a bit of poking around and indicated to me that he's heard additional other "rumblings" that recent Adobe Air updates may have contributed to Captivate "Blank Screens of Doom".

Any other developers running into similar issues?

Oh ... and my Chrome issue is also 32-bitOS/Browser, just as a FYI. FireFox and IE both play the CP pieces just fine though.
