I wrote a simple program to exercise new Italian words.
There is a 2 dimensions matrix; the first is the word to guess and the second 
is the definition. The program randomly asks the word with a 
JOptionPane.showInputDialog showing the definition, and after the user 
presses Enter, it shows the answer with a JOptionPane.showMessageDialog.
Then, the user presses ok and it goes on with the further definition.
However, sometimes this window appears blank. No writings or buttons, neither 
error messages. Nothing.
The only thing to do is to stop the run, and since I keep the history of the 
words already asked, it's very annoying.
I noticed this started happening after a big number of data inserted in the 
matrix (some hundreds) and now it happens let's say every 2-3 times I make it 
run (words asked are about 50-60). It didn't happen while test phase, when 
words were only 10-20. It has nothing to do with the correctness or the 
answer typed.
What can it be? How can I fix this? Thank you
