EXCEL TABS AND CONTENT GREYED OUT

[spwm]

Hello,

Assistance desperately required. I am new to this forum and I am told that my problem will be solved.

I receive regular emails with excel spreadsheets attached and of late when i open them up everything is greyed out which means there is no content and the tabs and command icons are all greyed out as well.

I attempted all the trouble shooting available via google and they will all work if and when i am able to access these settings under advanced setting but once again these settings are greyed out as well. EXAMPLE: Display heading making sure the sheets are visible is selected is also greyed out.

Please see screen shots below and please assist.... I can open them if i save them and then open again....

Did you do repair on the Office installation?

Does the same happen on another machine?

I am having the same problem as the above person.  I haven't changed anything from the last time I used it and can't see anything but grey.

@spwm It seems that you accidentally hid your spread sheet, click alt+w+u. This isn't a normal hide, but rather a "hide the entire spread sheet".
