Question : Media Manager in Joomla 1.5.18 will not let me browse or upload

I have a Joomla site and thought that the Media Manager would allow me to browse and upload from my local directories on my pc. For some reason I cannot. Is that what Media Manager should be capable of doing or did I miss something here. Any support is greatly appreciated.

Also I just got a security threat via email from Joomla. I have 1.5.18 and cannot see where I can update to a later version. Is there something I need to do to keep my site safe from the security threat? I am not sure what to do based on the email I received.?

Using the code in the related post, consider what happens when adjacent_find sends left=(22,A) and right=(22,A) to isDistEqual(). The distances match, but the student ID do not match and so
       left.studentName != right.studentName
is false. So this pair is skipped by adjacent_find.

So, you won't even know from adjacent_find that there even were two entries = (22,A). So, you don't have to worry about getting 22 feet: A, A, C, D since 22,A will be seen only once.
