Wanted to report that the "browse" issue occurred for me in Firefox but not IE (ver 7.0)
Would love to.. **sigh** Unfortunately the charm and attraction of this WYSIWYG editor in particular is that DIYER clients who are not terribly tech savvy like being able to update/add content without needing to know/learn FTP.. (and yeah fortunately or unfortunately, FTP is a difficult concept for some to grasp..) So I explain the risks, try to show them the right way to do this, but most decide to accept the risk and use the file manager feature.. I'm always amazed how convenience always wins out over security for many end users.. **sigh**
