I have an NX-80 and have noticed a problem with ePocrates and Graffiti 2. When you attempt to write any letter followed by "i" in the search field, it writes an "l" as usual until you dot the "i" and then it backspaces and writes the "i" However, in ePocrates, it seems to backspace more than once and erases the previous letter. That makes finding "Zithromax" difficult because the "Z" is always being erased.
