Hi Vinodh,
Thanks for your reply.
Normally the dialogue shown in your reply is what I would use to display all the icons .
However on the dialogue window I had, the option shown in your red circle was not present and therefore could not enable the hidden icons all the time .
In a another reply there was suggestion how to get into the normal
Control Panel. where I could see this
CUSTOMIZE option icon as shown in the red circled dialogue window .
I activated it there and this has now allowed all the icons on the taskbar to be viewed.
I wondered if there is a bug that prevented me seeing the CUSTOMIZE option I normally expect to see as you described.
Thanks for your help.
