I believe the patches offered in that post were to address an issue that sometimes occurs with Resume Data bookmarking in certain LMSs.
If you are currently using Resume Data bookmarking, try disabling it by checking the box in LMS Customisation dialog to Never Send Resume Data. If that resolves your issue, you at least know what is causing it.
In cases where there are a large number of variables, the only way to diagnose the issue may be to remove as many variables as possible first. Then when you finally get to a stable version that does not misbehave, you then re-introduce the other components to find the one/s that re-introduce the issue.
So, in your case, you may need to look at how your developers are 'converting' the authorware content in Captivate. Make sure they recreate everything using Captivate components, and insert the images via the approved menus etc. I'd also temporarily avoid using this Riverbed compression solution until you have established the cause of your issue. It may be interferring with something.
Thanks for the reply. This is extremely helpful and interesting. I will look into this with GreenLight and respond with our findings.
