Java RDP Keyboard Issue

Hi, can someone help me, I'm trying to use the following java rdp applet lixia-javardp - open source Java RDP client for Windows Terminal Services - Google Project Hosting, however the question mark "?" key does not work when typing through the java rdp client. Whenever I press the question mark "?" key a number sign "#" appears instead. This website lixia-javardp - open source Java RDP client for Windows Terminal Services - Google Project Hosting has the source, however I don't know much Java to try to fix the issue or how to re-compile from the source. If anyone can shed some light on this for me, I would greatly appreciate it. I emailed the devs about 10 times within the last 3 months, however they have not responded. I use the applet via a vpn client to connect to my servers via mac and linux, for the most part the applet works, however when I want to ask a question e.g in an email, I have to copy and paste the question mark "?" character from another email.

Hey guys, if someone can please help me with this it would be greatly appreciated. I checked the keymap file with a working version of the applet, however the keymap file is the same. This leads me to believe something is happening when I press shift + plus the key with /?. I'm not very good at finding the code which governs this and could use some help.

Can you make a small simple program that compiles, executes and shows the problem?
