Problem openbox + driver synaptics

Question

hi to all
i've installed on arch openbox. all it's OK except for one boring thing:
i have a synaptics touchpad so i've installed their driver and i've configurated it through HAL .fdi file ( because i haven't xorg.conf )
then the double-click has became three-click,
examples: in thunar to open a folder i double-click on it, NOW to open a folder i must click three times !!!! it's very very boring
HOW i can fix it ???
PS: with gnome as DE i haven't any problems, only with openbox ....
PS 2: all software is up-to-date, it's a fresh Arch install ...
thanks to all

Answer 1

Works perfectly here. Openbox and Elantech touchpad (essentially the same as Synaptics) on an EeePC 901.
/etc/hal/fdi/policy/99-x11-synaptics.fdi:
<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
<device>
<match key="info.product" contains="ETPS/2 Elantech Touchpad">
<append key="info.capabilities" type="strlist">input.touchpad</append>
</match>
<match key="info.capabilities" contains="input.touchpad">
<merge key="input.x11_driver" type="string">synaptics</merge>
<merge key="input.x11_options.TapButton1" type="string">1</merge>
<merge key="input.x11_options.TapButton2" type="string">2</merge>
<merge key="input.x11_options.TapButton3" type="string">3</merge>

<merge key="input.x11_options.HorizTwoFingerScroll" type="string">true</merge>
</match>
</device>
</deviceinfo>
Selected parts from /etc/rc.conf:
MOD_AUTOLOAD="no"
MODULES=(!pcspkr evdev atl1e rt2860sta acpi-cpufreq ehci-hcd usb-storage pciehp evdev psmouse intel_agp snd-hda-intel i915)
In ~/config/openbox/autostart.sh I (among other things) have this as well:
syndaemon -d -t -i 0.5 &
