Description of problem:
After upgrading from XFree86 v. 4.0.3 to 4.1.0-15 via up2date
I could no longer emulate a 3-button mouse on my Sony VAIO PCG_XG19
laptop.  I found some references to this online but no solutions
other than a mention of a similar bug being fixed in the next update
to XFree86 4.2.0 (4.2.1? 4.3.0?).  The config file is
/etc/X11/XF86Config-4 and the option is:

  "Emulate3Buttons" "on"

Reverting to XFree86 4.0.3 again (from ftp.redhat.com RPM) has
fixed the problem for me but I'm seeing weird font issues now so
I'm clearly out of sync beyond what RPM dependencies can control.

Version-Release number of selected component (if applicable):
4.1.0-15

How reproducible:
Always

Steps to Reproduce:
1. Run X on my laptop with Emulate3Buttons set in XF86Config-4
2. Try to produce 'middle' button click

	

Actual Results:  Nothing.


Expected Results:  Middle-button action.
