I have WMM Ver 12 on Windows 8 machine, with all the latest updates installed. I have even uninstalled an reinstalled Essentials to try and solve this issue, but it still occurs at times.  I am new at using WMM, so maybe I'm missing some options that need to be enabled.

My problem is that the captions I have put into my movie, ones I have placed at various places throughout, will sometimes move around for unknown reasons. These changes seem to the captions toward the end of the movie, and usually some of these, from some seemingly arbitrary point and throughout the end, will move closer to the beginning of the movie. One or two captions may even duplicate themselves so that two identical captions appear together in the resulting mess. I have had this happen several times and I am very frustrated with the difficulty of using WMM.

I have tried searching your web site and the web in general. No one seems to be able to offer solid advice on how to keep these unintended "movements" from occurring.  Is this issue just a failure of the WMM basic design? If so, let me know and I'll go elsewhere for a better product.

It seems as though a user should be able to anchor a caption to a picture of video clip -- not to a numerical time in the video stream. That way the caption follows the picture or video, no matter how much editing of the video is done before or after the caption. Is this not so? Can you not anchor a caption to a specific picture or video and have the caption not move around (that is, jumping to unrelated pictures or video frames) when editing unrelated sections of the overall project? Please, address this specific question -- is this really the basic design of WMM?

It seems from the questions I have read on the internet that many folks have this specific problem, yet there is offered no solid advice or fix that I can find. Please give me some specific and solid advice, if it is available.
