I was trying to test the
zoomin story view in two different wikis and it completely locked me out of them. Pages appear to render for about a half second, then the title turned vertical and the screen is blank. This is probably an unfortunate side effect based on my particular set of plugins and tweaks, but it was very disconcerting. The main tiddler page worked, but no way to access Control Panel to revert to a different story view.
This is on a Mac running under Bob's server thingie (downloaded executable)
Fix: under each TW directory (separate for each wiki) there is a tiddlers folder - inside there, sorted by date, near the top is a file named $__view.tid - delete it - this restored each wiki to the default view immediately.
Note to self: stay away from that story view!
