Install beta3 on a Notebook with an internal PS/2 touchpad and a connected USB mouse. When anaconda's mouse setup comes up, pick "Generic USB 3 Button mouse". Click OK. You still can't use the external mouse during installation. Mouse settings after installation are ok.

[the duplicates were caused by network flakiness - got timeouts on submission]
Were you trying NFS, FTP, or HTTP?
Umm... The problem doesn't have anything to do with the installation method. It's quite reproducable with all NFS, FTP, HTTP and CD-ROM installation methods. The comment on network flakiness was just explaining why I submitted the bug 3 times - "Submit Bug" gave me timeout error messages, but apparently, the bug got into the database nevertheless. You can safely ignore that part.
I don't see this with either CDROM or NFS installs on my Compaq Presario 1700T laptop with a Logitec USB wheel mouse.
What kind of laptop?
Dell Latitude C800
Brent, is this behavior even "fixable"?
I don't think that this is something I can fix. The mouse that you pick during installation has no effect on the mouse at that time. It won't take effect until X is restarted, which in this case means rebooting the machine after installation. I think it is up to the BIOS to decide which mouse it is going to use during installation. On my Compaq, if I plug in a USB mouse, it disables the onboard mouse. It seems that the Dell laptops behave differently. There's not much we can do about that.
Except for restarting X if the mouse settings have changed.
Or, alternatively, doing the right thing(tm) and making X mouse drivers modular so it can handle changes at runtime... *runs*
