Word Replacer II
O problema é muito chato. Todos os botões quase não respondem sempre. Por exemplo, para fechar uma janela e uma pasta do navegador, são necessários vários cliques e mais de 30 segundos.
Se o sistema estiver inativo por alguns minutos, todas as janelas congelarão e mostrarão "A janela não responde" e eu preciso forçar a saída.
Estou usando o Ubuntu há quase sete anos e nunca enfrentei essa situação.
Por favor ajude.
