Enable clients wo attach files to web-based email apps (i.e. GMail)

I am trying to set Sitekiosk so that clients can attach a file toa web-based email such as gmail. I have un-selected "Block HTTP post file uploads and I am getting the following error in the log. 20 0000 2013-04-19 12:46:12 -0500 [SiteKiosk] Notification: According to the windows monitoring rule(Title:'Choose file*' Class:'*') the window (Title:'Choose File to Upload' Class:'#32770') will be closed. I know that I make the entry in the "Settings" tab for "Block system critical windows & dialog boxes". I am just not sure exactly how I need to make the entry. Is this then a child entry under the "Choose File", or is it it's own entry under the Dialog Box and Windows mangement???? Thanks
