I have two WIN 98 home edition computers.
When I put in above WWW address I get two different results for studying for the General Class License.

The newer computer, more memory and faster, shows the test wall to wall, making the test very easy to read.

The older computer, has very annoying bright orange moving dynamic ads bouncing all over the place on both sides of the test.

I have reentered the WWW site numerous times on the older computer and cannot get rid of the ads. I appreciate space advertising but find these ads very distracting when trying to study for a test.
The newer computer is used for accounting etc and is not as readily available as this older computer which is being used solely for Amateur radio purposes.

How can I stop the ads on this older computer?
