This can be resolved by changing the font under Tools>Options>Fonts. Changing the font to System or Lucida Sans Unicode will display the script correctly. After saving your Fonts Options settings, you may need to close and reopen Connexion for the changes to be reflected.
This may also help with issues with other language script displays. If you have tried the above and are still seeing misaligned script, please send a description of the issue along with a screenshot of a record showing the misaligned script and a screenshot of your Fonts Options settings to OCLC Support.
