How to prevent CCS from locking up when changing languages?
If you change the Windows language setting while running CCS it is possible to hang CCS. There is a fix in CCSv4.0.2 and later to help with this (Asian languages) however if you still experience the problem you may need to adjust a setting in Windows XP. This is more frequent with Cyrillic languages. Go to Control Panel -> Regional and Language Options -> Languages -> Details -> Advanced. Turn on the option for “Extend support of advanced text services to all programs”. Also, the problem was not observed in Windows Vista or Windows 7.
