Seths problem seems to be that Jaikoz is still using Quaqua look and feel when it should in fact be using the satndard OSX loook and feel now. Ive asked Seth to do the following and I post it here in case anyone else having the same issue
Please go into Preferences:Appearance
Note what is set
Try changing to something else, if Mac OS X change to System, or if System change to Mac OS X
Restart
If that doesnt solve the gui problems and the performance problems then you’ll need to delete your settings.jai file whicc will mean losing any changes you made to your settings and you’ll need to reinstall your license:
Close Jaikoz
Delete ~Library/Preferences/Jaikoz/settings.jai
Start Jaikoz
