Web Designer MX (v8) Just Launched

[UnmeteredIIS]

Got a problem when publishing, keep getting "Internal program error 58.w.fi.nd" , after clicking "ok" it still publishes. Wierd

I have solved this issue, however, it is still a MX bug far as I can tell.
1. Open up a blank page and the double click or drag & drop...
2. Cut the video or audio player...
(Xara call them Placeholders located under Web Properties)
3. Navigate to the page you want the "placeholder"
4. Paste it in, however, you may still have mime/issues.

I have not dug into the issues bugs, however, I know that I
do get them probably due to mp4,mp3 format.

It seems that Xara MX only works with certain formatted
audio/video files... at least you will be able to bypass the
error that you mentioned.

Also someone mention to use "save as..." instead of "save" if you are getting a save error.
