is_dir on WIndows

I'm having a problem I haven't encountered before. I'm using PHP 4.3.4 (upgrading the 4.3.9, but humor me) on Windows. I'm using the following code snippet to try to get all the subdirectories of a directory into an array. $maildir=MERCURY."/MAIL"; $handle=opendir($maildir); // echo $handle; while ($file = readdir($handle)) { // echo $file; // echo is_dir($file)."<BR/>"; if (is_dir($file) && ($file!=".") && ($file!="..")) { $users[]=$file; } } What this should do (if I'm not a complete idiot), is put all the true subdirectories (excluding . and ..) into the array $users. There are two additional subdirectories under the $maildir directory. However the array is empty. As you can see, I tried echoing out $file and whether it is a directory, but it came up as not recognizing the directories as such. With the echos above in place, I get the resource handle, and it echos everything you would expect except that is_dir() fails to recognize the directories. It DOES recognize . and .. as directories, for some bizarre reason. And no, I can't switch to linux. Any ideas?
