I use English version of Comodo Firewall Pro under Polish Windows XP.
A problem arises when adding na Application Control Rule, in the case the application path contains some Polish characters. The application path written in the registry is wrong and the rule becomes useles, i.e. CFP is always asking if the application should gain a network access.
The problem can be overcome by correcting the application path in the registry:
I hope this wrong behaviour of CFP will be corrected. Maybe it also occurs with other localized version of Windows.
