JOptionPane Input Dialog is blank

Hi, I'm hoping that A) this is the right form and B) this is not a duplicate question. I didn't find anything exactly like it in a search.

Anyway, I'm new to Java and working on examples inmy schoolbook. When I run the code below, I get a blank window titled "Input". My only options are to Enter through the inputs, at which point I get a NumberFormatException because I haven't entered any numbers. I think my problem might have something to do with my Java versions. I believe I'm running 1.4.2, but 1.5 is installed on my system as well.

Can anyone help? Thanks!

. . . and what are you writing in the blank space on the input dialogue?

must be the version...

I compiled and ran using 1.5.0_07 and it worked just fine

Hmmm, I'll have to figure out why it doesn't like 1.4.2. I got the example from a book written for 1.3, so I would think it wouldn't require a later version. Unfortunately, I need to learn 1.4.2 specifically, since that is the version used on the program I was hired to maintain and word here is that there are no plans to upgrade to 5 or 6 anytime soon.

Campbell, to answer your question, I would type an integer in the dialog if it showed a box in which to do so. However, the entire dialog is blank.

Thanks for your help, guys.

maybe they would let you install 1.5 in your local area, just to see if it works?

Either that or re-install 1.4.2

All I know is that your code is fine, so there must be something wrong with your environment or JVM

I think Scott Cook is right.

In case anyone's still interested, I got the answer to this problem from someone on the Sun forums. I had to reduce my graphics acceleration by about three notches to make it work.

Thanks for your help!
