Here's a weird one. Our university health system uses a web form for text paging. The text box where you enter the text page content looks just like any other zoomed text editor field. You cannot type the letter "t" in this field using OmniWeb (currently using 5.1 build 113108 but observed previously v5.9). For some reason this keystroke is completely ignored. This does not matter if the text field is zoomed or static on the page. Works fine with other browsers. This site is on our intranet, so I can't post a link to it. I could possibly grab a source snapshot if someone from Omni wants to see that. I'm not using any custom mapping of this key which I am aware of.
