Excel 2007 - shortcuts are not working
 

Hi,
in our company, on all computers (we have Toshiba Tecra notebooks if this
matters, Vista Business PL) we experience the same problem with shortcuts
when using Excel 2007 (PL, stands for Polish edition). After certain period
of time when you are working in Excel shorcuts stop working. E.g. when you
press Ctrl+C then dialog box appears with question about removing a column or
row (!!??). It's really frustrating. Is there any solution or patch available
for this ?
