Invalid zoom ratio : 0.0

We've encountered this error on two different machines (Win7, i5 processor, nvidia graphics, jasperreports 3.6.2)

 

SEVERE: Page paint error.

Apparently it is not the cause why jasper reports won't work on these machines. Haven't figured it out yet what the problem is, but creating an empty report didn't work either (iReport just hanged).

The weird part is that after this error showed up in the console  http://bugs.sun.com/bugdatabase/view_bug.do;jsessionid=d664a5d10daa4fffffffffaf1ae96143e5016?bug_id=6957067 everything started working again.
