Learners Getting Stuck Randomly in Courses

Hi Steven, thanks for the response.  Yes, I should have mentioned...we have worked with our LMS vendor (Oracle).  I provided them with debug logs.  They responded with a test file (I'm not sure which product produced that file--it's not Articulate products) which worked just fine:  upon disconnect, the course displayed an offline message; on reconnect, the course reconnected to the LMS and continued just fine, capturing the results perfectly.  So Oracle is saying it's our Articulate output.  I feel like I'm stuck in the middle with Oracle and Articulate pointing fingers at each other.  I'm digging through the output files of the Oracle sample course and a Rise course to try to find what's different, but there are so many files, it's like looking for a needle in a haystack...and I'm not super familiar with xml or js.  :(
