I'm afraid I can't do that, Dave
I was looking around at screen reader products to get a feel for what they are like.
I made the mistake of downloading Hal™ from Dolphin Software (the lady holding glasses is such a generic stock image I recognized it without my contacts in. The blue link on top of the blue dolphin is nice.)
Did I learn nothing from 2001? The name should have warned me off, but I waded right into the artificial stupidity.
First off, the Hal™ software has a 30 minute demo period. Not 30 days, 30 minutes. Apparently this is about the same as JAWS, the leader in the field.
So I tried to change the settings and the best I could get is 1024x768 with 16 bit colors. I shrugged, uninstalled all three packages the HAL demo install, and rebooted.
The 16 bit setting was still the best I could get! You understand I've been doing 32 bit for a month now (with 64 Meg card my brother, a bleeding-edge gamer, no longer found adequate.)
For those of you wondering what bits are, I have a custom background with lots of swirling Jovian clouds. 16 bit color makes it look grainy and nasty. 24 or 32 bit means nice and smooth full color mode.
Every time I tried to use any 32 bit mode, it snaps back to 640x480, at 256 colors no less. Unbelievable! Finally, I re-installed my video drivers and that solved the problem.
Talk about anti-social software! There is an expression among hikers and cavers: Leave it as you found it. This is what an uninstall must do.
