If I have a php-file with a "//"-comment in the last line (*) and try to format it (with ALT + SHIFT + F) Netbeans depends for between 10 and 60 sek. After that the file is not formatted!

If I try to autocomplete a class/function (with STRG + SPACEBAR) depends for ca. 10 sek and then the letters that I typed are missing.
I can autocomplete namespace.

If I delete the "//"-comment all works fine.

(*) for example:
[code]
<?php
$var = 'value';
// <-- last Line!
[/code]

PS: I hope I have done everything right - this is my first report.
