Not sure how it would affect you playing games online but the CiceroUIWndFrame problem necessary for the Alternative User Input modules in Microsoft Office.
Hopefully this should stop any problems -
Click Start -> Control Panel -> Add Remove Programs -> Highlight Microsoft Office and click change -> Click next with add or remove features marked -> Tick 'Choose advanced customization of applications' -> Click Next -> Click the plus sign next to 'Office Shared Features' -> Click the plus sign next to 'Alternative user input' -> Make sure there is a red cross next to both speech and handwriting -> Click update.
You may need the Office installation CD for this to successfully update.
Hope it helps?
