I am running ReactOS in VirtualBox on Mac OS 10.5.7. When attempt to launch Word Viewer 2003 the program give me a error saying that "The instruction at "0x311250d" referenced memory at "0x0000000c". The memory could not be "read"". Then it caused the task bar to disappear. To get it back you need to restart ReactOS.
