Gayan, that works. However, I don't want Google as my home page. When I leave the blank page for startup, but make my home page subscribed threads in this forum, the same thing occurs as before.
Has anyone else tried changing their home page to subscribed threads in this forum?
EDIT:
Damned strange. After experimenting with Gayan's suggestion, I changed my home page back to subscribed threads in this forum, and the problem went away.
EDIT:
Bloody orc had the answer. The home page setting is for all tabs existing when the "Use Current Pages" button is clicked. I had missed the "s" in "Pages".
