Ambient light measurement randomly doesn't start (Spyder 4)
Display Calibration and Characterization powered by Argyll CMS

I'm using Spyder 4 Pro. The "Measure ambient light" button works only rarely. In most cases I get the "Please wait" dialog and nothing is going on for tens of minutes. On the console I can see:
Place instrument on spot to be measured,
and hit [A-Z] to read white and setup FWA compensation (keyed to letter)
[a-z] to read and make FWA compensated reading from keyed reference
'r' to set reference, 's' to save spectrum,
'f' to report cal. refresh rate, 'F' to measure refresh rate
'h' to toggle high res., 'k' to do a calibration
dispcalGUI: Waiting for send buffer
Rarely the measurement works (about twice within two days), but in most of the cases it ends up waiting for ever.
Using dispcalGUI 2.1.0.0 on Kubuntu 14.04 64-bit
Instruments with monochrome ambient sensors (like the Spyder 3 and 4 Pro/Elite) currently cannot be used to measure ambient with dispcalGUI stable. Please try the latest development snapshot.
Are you sure its monochrome? using the spyder4pro software recommends setting the whitepoint to 5800k... after using the ambient sensor?

According to the Argyll CMS documentation it is.
I have the same problem with the latest development snapshot.
Which version of Argyll CMS are you using?
