[Plugin: Tweet My Post] plugin blocking single word hyperlink

I started having a problem today when I went to do a single word hyperlink in a post. The screen would grey out but the hyperlink tool box would not come up.

I deactivated all plugins then re-enabled until the error occured. It seems to be the Tweet my Post plugin that is causing the problem in both Chrome and IE.

This is new…successfully tweeted posts two day ago….
