Geepers,

Making it difficult to complete transactions since a portion of the top of
an inset page is covered by a white bar so I cannot get to the button
needed to proceed

If you feel daring you could rightclick that 'white bar' and select "Inspect
Element (Q)" from the context menu. Than wait a bit until the blue
text-selection bar in the lower half of the screen (the "Inspector" window)
steadies out, and than use the up/down arrow keys to move the blue bar up to
select a bigger portion of the HTML content (encompassing the whole 'white
bar'). Than rightclick on the highlited line(s) and select "delete node".
Presto! The 'white bar' is gone and you can reach that button.

Don't worry though, a refresh/revisit of the page will again show it (in
other words, you do not even need to feel *very* daring, but just a bit.
:-) )

If you use that page more often you could do the same (removing the 'white
bar') using a plugin named GreaseMonkey. That would need some knowledge of
JavaScript though ...

Regards,
Rudy Wieser
