no way i can write some simple into that box!
i unstalled hw image plugin, deleted it, dowloaded and installled a fresh version, shut down my wordpress admin panel for 12 hours but the situation remains the same.
note: i must say though everything went fine the first time i tried to enter some text 2 days ago. problem appeared after that.
it'a real pity since i'd like very much this plugin and would be prepared to pay for it provided that it works.
