TEST STEP FAILS IN DESKTOP APP. ON JAVA WITH THE MESSAGE "CANCELLED BY USER"

I launch the test for Desktop application on Java and sometimes it falls of with the message "Cancelled by user". However this step passed an hour ago, for example, or if this step was launched separatly, not via the whole test. Morever, I asked my co-worker to launch these tests and he could manage with passing the tests. Have anyone had the same issue whenever?
