How to overcome this System Error &H80004005 (-2147467259)?

[PK]

Hi,

When I try to copy or paste or undo or save, for any of these actions I am
getting a pop-up box with system error as follows:

system error &H80004005 (-2147467259). Unspecified error.

If we give continuous number of clicks on "OK" button, then only pop-up box
or dialog box goes away and allows us to do the any one of action in need.

Please help me in this.

Thank You,

Regards,

PK
