D600- USB Mouse stops responding in docking station (Options mentioned elsewhere here do not help me)

Hi, I'm new to this forum and appreciate that it exists for potential help not found elsewhere. I have a D600 with D/Dock that has similar problems that others have mentioned here, with the exception that I'm using a Dell certified USB mouse and have XP-Pro with all available patches. So, there is no new mouse driver for me to try nor is there anything I can patch on the OS. The same mouse, and another Kensington I use for travel, work flawlessly when hooked straight to the laptop. The only problem is when hooking through the Docking Station. Others I work with have also experienced this to different degrees. For me, it's a minimum of twice a day and sometimes well over 15.

BTW, people who are using the same laptop and D/Dock with MS and Compaq PS/2 mice don't have any problem here. People in IT here tell me they've had a lot of complaints about this situation and have been telling people to revert back to the PS/2 mice they had with their desktops. Perhaps I'll just have to assume this Dell setup will never work properly with a Dell USB mouse...?

This seriously looks like a docking station issue to me and am looking for any ideas on what to try next, if anything.

Thanks!
