What steps will reproduce the problem?
1. Create a configuration file
2. Start jkeys using the configuration file and firefox
3. Start playing (works only for the first few button presses)
4. jkeys stops working

What is the expected output? What do you see instead?
It should continue working as expected, but instead it stops working after a 
few button presses.

What version of the product are you using? On what operating system?
I synced to the latest version from the svn repo. I am on 64 bit Ubuntu 9.10 
(Karmic) with 2.6.31-22-generic kernel.

Please provide any additional information below.
