Hi Don,
Thanks for all the detailed information you have shared on this thread.
We haven't seen any report in the past about text disappearing or colors being wrong, all this seem to make the add-in totally unusable.
We support only the versions of Windows supported by Microsoft, meaning we no longer support Windows XP (http://windows.microsoft.com/en-us/windows/end-support-help). If this issue is related to Remote Desktop + Windows XP I am afraid we can't do anything about this. If the issue is related to Remote Desktop on any Windows version then a bug report should be created at
http://bugs.mysql.com with all information needed to consistently reproduce the problem.
Best regards.
