If Adobe Creative Suite 2 includes either Adobe Type Manager Light or Adobe Type Manager 4.0 then this could be the problem.
This advice comes from Microsoft:
SYMPTOMS
When you are using a Standard 101/102-Key keyboard or a Microsoft Natural PS/2 keyboard, you may receive the following error message when you try to put the computer into Standby, Idle, or Hibernate mode:
The device driver for the "Standard 101/102-Key or Microsoft Natural PS/2 Keyboard" device is preventing the machine from entering standby. Please close all applications and try again. If the problem persists, you may need to update this driver.
CAUSE A
This behaviour can occur if Adobe Type Manager Light or Adobe Type Manager 4.0 is installed on the computer.
RESOLUTION A
To resolve this behaviour, use the Add/Remove Programs tool in Control Panel to remove Adobe Type Manager Light or Adobe Type Manager 4.0, and then restart the computer.
CAUSE B
This behaviour can occur if a program installs a kernel-mode driver that attaches itself to the standard keyboard driver (I8042prt.sys) and does not support Plug and Play I/O request packets (IRPs). Examples of programs that exhibit this behaviour include:
- Pgpdisk version 6.02 and 6.5 (installs Pgpmemlock.sys and Pgpdisk.sys drivers)
- Adobe Type Manager version 4.0 (installs the Atmhelpr.sys driver)
RESOLUTION B
To resolve the behaviour, contact the manufacturer of your program to inquire about the availability of an updated version of the program that is designed for use with Windows XP.
To work around this behaviour, uninstall the program that causes this behaviour, and then restart your computer.
