Are you using a version of flash greater than v10?

On this particular win-98 system, I have flash version 11.6.602.171.

I'm using 10.0.45 in W98 but notice, increasingly websites are
requiring v11, eg:

I'll check that out later, because this computer is currently very busy
downloading the entire Star Wars saga (6 blue-ray disks) from 8 file
lockers at the combined rate of about 800 kbytes/sec. This is about 10
gb per movie. I'm using jdownloader for this task.

Can flash v11.1 (latest I care to use) be installed? Work ok?

Yes, the version of flash that I have (see above) works just fine.

You need to install KernelEx for flash version 11.x to work on win-98.

I've written plenty of "how to" posts here in this newsgroup over the
past year regarding how to install Flash v.11 on win-98 - they aren't
hard to find...
