Task Bar - keeping it visible

I’m attemtpting to move from OpenOffice to LibreOffice.
In LibreOffice, I use the Standard task bar and have customized it with a few icons I used to use on OO.
When I open a spreadsheet, I must go to View → Toolbars → Standard to display the toolbar but when I work on the spreadsheet, it disappears.
Is there any way of keeping the Standard toolbar visible at all times?
Thanks,
Dave

Can that help?
