CategoryRemoveSymbol()

//Remove Symbols from Target Watchlist
for( i = 0; ( sym = StrExtract( Issue_TargetList, i ) ) != ""; i++ )
{

    CategoryRemoveSymbol( sym, categoryWatchlist, Issue_TargetNum );
}

The code above works OK except when watchlist contains old symbols that are no longer in database. All current symbols are removed properly .... old symbols remain in list.
