I am using "imagebrowser" and "save" plugins. If I enter text into an alt tag, e.g. "coffee beans", I can go into source view, return to standard view, open the image dialog again, the text always remains unchanged. However when I click the save button, the spaces are stripped from all the img alt tags, so that "coffee beans" becomes "coffeebeans" etc. Other characters such as apostrophes and periods save without any issues.
Does anyone know what can cause this?
