OPC DataSocket error 42 in writing negative values

Question

I was playing around with OPC and using the DataSocket pallete. Although I've used it reliably for a while and am content, I was baffled by one error. I was hoping someone could explain why this error occurs or how to solve it.
In the NI Distributed System Manager I've created an Shared Variable of the type single, with Read/Write access.
Problem
When writing a value less or equal to 0 to an OPC URL, I get an error 42. When using the equivalent PSP URL, I don't get it.
Using this VI snippet code.
I get these paths and errors:
This error 42 comes for all values below zero and for zero. For all positive values I don't get this error. What's the reason for this behaviour? In my humble opinion this is not wanted behaviour, as OPC tags should accept the whole value range of the single.

Answer 1

White spaces are allowed in OPC URLs, so that cannot be the issue.
I've tested with another LV2013 computer and NI Distributed System Manager 2013 and got the same errors. However, when I tested it on a LV2012 and NI DSM 2012 it was all working. Quite strange.
Now I'm wondering if it's something local or that the bug was introduced in the 2013 distribution and if it has been solved in the 2014 version ...
Could someone test it on LV2013 and/or LV2014, just to check if the problem occurs for other installations in LV2013 and if the problem has been solved in LV2014? Please indicate LV version and DSM version.
