zend studio 總會有些莫名其妙的bug

上傳一個文件，提示信息如下：

Failed Downloading files from : [advancedSearch.function.php] to: [advancedSearch.function.php] error message:[Operation failed. Security violation] date [Tue Sep 27 15:31:33 CST 2011]

---------------------------------------- Upload completed -------------------------------

[0] files where uploaded to server time elapsed: [16] date [Tue Sep 27 15:31:33 CST 2011]

總是上傳失敗，提示是因爲什麼安全障礙導致的，鬱悶。問題在哪裏呢？網上又沒有什麼太多可用的信息，

有解決辦法的同行請留言，謝謝！
