Hi, all, 
I've installed the IDE 4.7 (win) with QNX6.5 on my PC and I've try to
generate a Photon application.
On the same PC I've have 6.3.2,6.4.1 and now 6.5.0.
IDE and QNX directories are on D: partition.

In the IDE4.7  (6.4.1 environment)  I' ve created  a simple appBuilder 
application using a workspace placed on a network disk  (H:).
When I do generate UI in Phab development environment or simply to save it,
 the error report:
 "command approto -p *.c *.cc  *.cpp >proto.h  died(127)"

the 6.5.0 env. has the same problem.

If I select the 6.3.2 environment, all works fine.

Now, if I copy the same project on a location on the D: disk and I import it the same 
network workspace, all works fine in both 6.4.1 and 6.5.0 envs.

So, it seems that the appBuilder released with >=6.4.1 works fine only
if the project is on the same driver where appBuilder is located....
Any idea ?
thanks
