Zend Studio has some very nice features like code completion for your own classes, project setup, SVN integration & extended debug options. But... after I've tried the v.5.2 trial for one week I gave up because of some unacceptable problems:

- It crashes very often. It simply suddenly dies on Windows XP, and if you had things unsaved you lose them. Unacceptable.

- After you have done a find & replace action, you can't go back. It simply moves the cursor over the screen when you press CTRL+Z, without undoing anything. Unacceptable.

thanks for the great site.
