Thank you for your answer.^^
I'll show you the message of a red "x" sooner or later.
I can' t find that error message right now.
Anyway, off the top of my head, I think it may be possible that this problem has something to do with "Heap space". Whenever I click
'renew' button, I saw a red "x" and also "out of memory : java heap space" error message. what do you think? But what you should know is "it work properly every first time". Only doesn't work after clicking "renew button".
Ok, I'm going to go to find an error message!!^^; thanks again!
Heap space is an amount of memory that Java grabs and uses for whatever memory demands that the applet makes (simplified explanation.).
It sounds like there is some problem with the applet. Possibly it is leaving Java objects from the first use of the applet in the "heap", and subsequent iterations of the applet are adding to the heap, causing it to be overrun. I suggest that you avoid clicking the applet's "renew button", or speak to the applet supplier.
