Having installed Acrobat 10.1 update, the pdf maker in Windows fails after around 3 seconds with no error message. When opening a file with a PAGE ACTION to open a separate file in the same window, Acrobat crashes. The same problem is evident with Reader 10.1. These were not evident in 10.0.1. Computer is operating XP SP3 and Windows 2003 SP2. (It appears that the later issue is not evident on a Windows 7 machine)
