I can't open the Device Manager on my machine. The exact error message that comes up is:
The procedure entry point ?PickIconDlg@@YGHPAUHWND__@@PAGIPAH@Z could not be located in the dynamic link library mmcbase.DLL.
I'm not sure exactly when it started; I just noticed it when I was having some virus issues last month. The virus seems to have been cleared up, but this weird problem remains.
(P.S. I have SP3, but there was no option for it in the 'Product' list.)
