Hi there, I just can't find the solution to my prob!

I type this -> mysql_connect

then the code hint helps me to fill in the required parameters, for example the host. PHPEdit opens two double quotes and lets me type in what I need. Then, to leave the double quote and put the cursor automatically right after the second quote, I usually press the tab-key. But this doesn't work with PHPEdit. Works very fine with aptana or eclipse, but not in this app.
Why not? Where can I fix this???
