Ciao a tutti, avrei bisogno di usare questo codice che mi gestisce lo scroll dinamico di un campo di testo con contenuto esterno.
Questo codice è nato per flash 5, ma io avrei bisogno di pubblicarlo per Flash 7 in maniera da poter caricare anche le jpg all'interno del campo di testo (tramite i tag html), ma se lo pubblico in flash7 avvengono degli errori, ad esempio scrollando usando le freccette ("arrowup", "arrowdown") non si muove la barretta ("scrollbar").
Qualcuno sa dirmi dove sono i codici incompatibili o deprecated o chissa cosa?a livello intuitivo credo sia qks relativa all'oggetto "Text", che con Flash7 assume nuovi e più complessi significati... ma non saprei proprio!
Vi ringrazio molto, ciao!!
