Cannot open multiple pages in Calc

For printing multiple sheets or making mods to multiple pages I have previously been able to use shift and/or ctrl to highlight more than one sheet. For some reason this no longer seems to work. Press/hold ctrl and clicking another sheet does nothing.

Using 5.0.6.3 on Win7
Pse advise, thnx.

I just updated to 5.2.3.3…no joy. : (
…also note when I right click on sheets I cannot “select all sheets”.

Have all selected sheets the same page’s style?
