hi jonisantos / i am not sure, but it may be a priority class; the dnc & chrome, word, etc, may all have same priority
this means that the resources asociated with a running process are divided, and a new fraction is switched to the new launched process
this may lead to a subtle interuption of the dnc
if the dnc process would be asociated to a single cpu-core, and all other processes would be asociated to different cores, maybe you may avoid this error; try associating a single-core only to the dnc
try lowering the priority class for word, chrome, etc, or increase it for the dnc
try running a simpler application, that is less resource demanding : if dnc would be stable, than it may be a bus issue, that appears when applications with more resource demanding are launched; try using a more powerul pc
the controler no longer pings with the pc, or it receives a delayed answer; it may be possible that the hdd stops the data transfer, only for a fraction ( with negative impact especially if dnc read buffer has a reduced size ), so to read&load files of the new application ( try transfering data from a separate hdd )
the problem is not related to the dnc transfer, because it is stable on its own; it is more related to the way the dnc software and the pc manages available resources
contact the guy that developed that dnc ? kindly
