ciao a tutti!

ho scritto un software e uno delgi utenti ch elo utilizza ha il seguente errore.

lo script non ´´e altro che un timer su un form che esegue delle semplici azioni a intervalli regolari.

sapete dirmi cosa potrebbe causare il problema e perche solo a lui? .net installato, niente programmi strani, non riesco a trovare la causa.

grazie

ciao

igor
