Hello again, bummer the problem returned...
Can you kill one of the SPMgr.exe instances in Task Manager?
If so, does that remove the duplicate icon?
Look in msconfig/startup to see if there are two entries for SPMgr.exe.
If there are two, disable one and re-boot.
You can also download and run Sysinternals/Autoruns
and look for multiple occurances of SPMgr.exe. Sysinternals Utilities
If you find more than one you can disable it in Autoruns, and re-boot.
Autoruns has a lot more info than msconfig/startup...
Hope this helps,
