Bug on Global variables with build 940

 
It's seems that on build 940 there is a bug using Global Variables: when you add a GV all is ok, and you can perform normally other functions (modify and delete). But if you close the platform and reopen it you loose all changes. probably there is some problem with the copy of changes on relative file. Please advise if someone finds same behaviour.
 
Nor it's running the function GlobalVariablesFlush(), so you can't save your GVvalues between one work session and another one.
 

I can't reproduce the problem, if I change a GV by code, then restart MT4, the value is well saved.

Reason:
