[Blind-sysadmins] Anyone using Sametime on a Mac?

Hi, so I’ve recently taken a new job and the company uses Sametime for messaging. I have used this before a long time ago but am having accessibility issues now where I can’t read what was sent to me. Has anyone used this package, especially on a Mac and have any ideas for things to adjust? I have enabled the accessibility features under preferences with no luck. Any ideas would be most appreciated. Thanks Scott
