Hi John ... I just reproduced the issue (I did not need to make any changes to the configuration). I am not getting any error log (File>Error Log) ... the errors appear in the Communications Log window on the client. When the errors appear, the client does not register that there was a successful position update (the errors are not happening on 100% of the position updates, but, it is a high percentage) ... however, looking at GRLevel3 with the "Custom Spotter Network Positions" placefile activated, it looks like the position reports are being uploaded successfully, so, the error may be mostly benign (at leaston my end). However, with all of the slop in the Communications Log Window, it makes it really hard to know for sure that things are working. I will send a copied/pasted excerpt of the Communications Log window to the support email address.
