I may have just missed it, but I don’'t think anything has been posted on this issue. I administer a Wildfire server in the mixed-environment (Windows and Mac)office in which I work, using Spark on both OSes. Currently, the Windows version works great, but the Mac version seems to have a problem in which, if the Mac Spark client is sent a message but Spark does not have the screen focus, then the user cannot click in the message box to write a reply message. If this could be fixed for the next release, I can tell you that my users would greatly appreciate it! Of course, if any more information is needed, please let me know.
