When running the attached sample program an exception will be thrown in TcxSystemFontLoader's CompleteHandler. A single listener will be in the list that still points to an already freed TcxFontNameComboBox completion handler.
TcxFontNameComboBox registers two notification links during it's construction from the dfm, the second one when the FontTypes property is assigned. (A non default value has been set in the form designer)
During the destruction of TcxFontNameComboBox only the first notification link is removed, the second one is kept and will cause an access violation the next time the handler is invoked.
Hello Steffen,
Thank you for reporting the issue. It will take us some time to examine the cause of this exception.
