I've updated the development snapshot source code again, to reflect the latest fixes created in response to the various bug reports. In particular the following bugs with the ColorMunki & Spyder 3 are fixed: * easier to build on MSWindows by removing the need for the DDK, and now known to compile using VC++ Express 8.0 and 9.0 + SDK. * A memory allocation bug triggered when measuring a bright display with the i1pro or Munki is fixed. * dispcal/dispread black background option now operates after placing the instrument on the display. * On OS X the Manufacturers ColorMunki drivers now don't prevent Argyll using the instrument. * A too short press of the ColorMunki button for a scan doesn't result in an unrecoverable error. * Increased Spyder 3 low light integration time slightly. This probably isn't enough to solve its low light problems though. cheers, Graeme Gill.
