User has HP laptop, WINXPsp2 using Lotus Notes. When user prints a mail message he gets a calendar page instead. He reads the message, clicks on the printer icon then gets a calendar page instead. It doesn't happen every time, but randomly. I have watched him do it. He uses no specific pattern, just read the message then prints it from the printer icon.
Also, when he reads one message and moves it to a folder or deletes it, it doesn't necessarily go right to the next message, it might skip one or two then go to the next one. He reads his messages in decending (from bottom to top) order.
Any ideas on what's going on??
