Win 7 shortcuts / interaction problem

Hi there,

I have Win 7 Home Edition and on my former OS (Win XP Prof.) I had several shortcuts linking to some batch files. So after new installation of Win 7 it copied the shortcuts back on the desktop of Win 7. These shortcuts are working fine so far .... BUT .... now here it comes: I am also working with Microsoft Office Home & Student 2007.

So while I am doing nothing the shortcuts are working fine. When I am starting (e.g.) MS Powerpoint to work on a presentation the shortcuts still work fine. But when I start the powerpoint presentation to present on the screen suddenly the shortcuts do not work anymore. All of them ! Another Example: MS Word (out of the a.m. Office Suite). Once I have startet MS Word to be ready to type a letter the short cuts won't function anymore. After closing MS Office the shortcuts start working fine again !

Does anybody know this problem ? Any help is really appreciated !

Thanks,
Visi
