Macros only working during inital use of Solidworks session on specific machine

We have numerous macros which work fine throughout the company, however on 1 specific machine the macros only works during its inital use of the solidworks session.  After closing out of Solidworks session and re-starting solidworks the macros no longer work.  Hovering mouse over macro icon and clicking has no effect.  Could there be a registry setting or something?  Any suggestions, uninstall/reinstall, repair installation?  Unsure.  Again macros are working fine on all other machines throughout company.

Window7, SW2007 SP5.0

Thanks for any input and suggestions.
