I'm not sure how can I reproduce the error. It happened two times while working at the same project. If you want, I can give you the code I was working at (my email is )

The previous time netbeans had blocked and I lost the work I have done till the last save. Both times it had a warning : while I was editing and using the cursor keys, the down key had a different effect( seldom down, more frequent up_key effect). This time I saved (it saved well) and restarted netbeans.

grimlock81: Not sure, just noticed the error balloon

Third time I got this error. I'm sure there are much faster typers (I'm using Programers Dvorak keyboard under Ubuntu) , but it seems it is related to typing. The keyboard started geting the wrong keys.

whily typing
