I posted this question to the forum on 14th July but received no reponses, so
I am posting it again.

I have a macro set up which runs through its commands every time a combo box
in the worksheet is changed.

If I change the combo box with all the source data worksheets hidden then
for some reason hidden rows in that worksheet are unhidden. There is no VBA
code which specifies this.

If all worksheets are unhidden, changing the combo box does not unhide rows
and the macro works normally.

What could be causing this?
