Swf frame number detection no longer working in 11.5

Question

I have a movie that loads Flash swf files to sprite(41) and displays them at "displayslide" on the timeline. Some of the swf's have more than one frame, and on those frames are buttons to a video player further down the timeline at "showvideo". The button script picks up the frame of the flash swf, and the return button on the video player sends it back to that frame. Or it did until 11.5. Now it always sends it back to the first frame of the swf. Running a trace shows that it actually does pick up the correct frame, and the return button sends it back to the correct frame. But there seems to be a handling problem when it tries to redisplay the correct frame. I have managed to find a hack workaround by inserting a keyframe in sprite(41) and adding a script to the timeline which repoints to the correct frame. The problem is it now flashes up the first frame of the swf before going to the correct frame. Could this be a problem with the updateStage? The reason I say this is because I had to make the keyframe insert two frames long as one frame would not work
Here are the scripts:
--** Slideshow functions
global slideframenum, slide, lastslide
on showstart
  slide=1
  slideframenum=0
  lastslide=(the number of members of castlib "blank")/2
end
on displayslide
  member("slidenumber","internal").text= "Slide "&slide&" of "&lastslide
  sprite(41).member=member((slide*2),"blank")
_movie.updateStage()
  if slideframenum<>0 then
    sprite(41).goToFrame(slideframenum)  
  end if
  _movie.updateStage() 
end
Here is the script on the video button
on showvideo myvid
  --** myvideo show
  slideframenum=sprite(41).frame 
  go to "showvid"
  sprite("1").member=member(myvid,"videoavi")
end
This is the script on the return button of the video player
on mousedown
  go to "displayslide"
end
I have had to insert this on the timeline before "displayslide"
global slideframenum
on exitframe me
  sprite(41).goToFrame(slideframenum)
  slideframenum=0
end

Hi Joshua
I tried a stripped down version with a 3 frame swf simply dropped onto the timeline - the problem does not occur. That means I would have to upload the full movie as it draws multiple slides from an external library and drops them onto the timeline at runtime. This package was developed to replace normal training material and is used widely to train some 120 000 candidates per annum by several companies. As such I cannot therefore post the full movie as I have to protect the code that drives the whole thing.I will have to stick with McGyver fix for the meantime.
As each slide is pulled from a library, and the slide backgrounds from a separate swf library, I think that something new in 11.5 either has a problem with running multiple things at the same time, or has a problem in running a sequence of instructions.
