Mouse buttons hang on Dell C840 squeeze

[Paul Boughner <paulboughner@gmail.com>]

I have had a problem getting my mouse buttons to complete a click on
anything. This began after I wiped lenny and installed squeeze. If I
click on any button in the GUI, the mouse will hang and if I let it go
long enough I will get an error 'unable to capture your mouse.' To
complete the click I only need to touch the touch pad and it will
finish. If I keep my finger on the touchpad while clicking, it does not
hang at all.

I see some others are having problems that might be related. Anyone got
any ideas?
