As you might have noticed, recent changes at LJ may result in more markup errors than before if your entries contain incorrect HTML. Semagic has an option to automatically replace 2 spaces with &nbsp; because most browsers do not display consecutive space characters. But Semagic does not preform HTML parsing so if that option is enabled all such characters will be replaced though that is allowed only for text according to HTML standards. If you type several spaces within such HTML tags like img and they are replaced by &nbsp; the resulting HTML <img &nbsp;src=""> will be treated as error. In WYSIWYG editing mode that is not a problem because you do not manually enter HTML at all.
So if for some reason you want to type HTML tags manually it may be better to disable the mentioned option in Options/View. Additionally, the latest version of the client removes all &nbsp tags placed inside <img>.

Among other news, for the second time Semagic and LiveJournal were mentioned at Microsoft site (the first time was about bloggin plugin). Now it is listed as one of applications that may behave differently on XP SP2. "Live Journal Semagic, version 1.3.9.6, vendor Live Journal" is listed among other products like Unreal Tournament, Norton Antivirus and Office XP. Complete list is available here.
Please remember that for most of users Semagic works in XP SP2. If it does not work you can use a solution provided in this community several entries earlier. It was not working on earlier versions of SP2 about a year ago and only for several users.
