#4 Error processing function

[Uroc327]

Everytime I open a file with a line like this

template <class T> ABC<T> ABC<T>::operator |(T _abc) const

I get the error message

Error detected while processing function <SNR>67_Tlist_Refresh..<SNR>67_Tlist_Menu_Update_File..<SNR>67_Tlist_Menu_File_Refresh:
