[photran] Problem in using C/C++ perspective

[schroeder <jaygrey@xxxxxxxxx>]

Hello, everybody.

I've recently tried to install and use Photran, both under Linux and Windows, 
both as a standalone application and as an Eclipse feature, and in all cases 
I've experienced what follows.

Version of Eclipse: 3.3.0 Build M20070921-1145 
                                  3.3.1.1 Build M20071023-1652
Version of Photran: 4.0b3 w. CDT 4.0.2.200711280800
Problem: in closing a C++ project (i.e., working under the C++ perspective) 
after the (successful) build, Photran complains about the following:
________________
'Synchronizing Photran VPG (Time of error: dd month yyy hh:mm:ss)
Reason: org.eclipse.core.internal.resources.ResourceException: Resource 
'/dir_of_the_project' is not open.
Details: An internal error occurred during "Synchronizing Photran VPG".
org.eclipse.core.internal.resources.ResourceException: Resource 
'/dir_of_the_project' is not open.
_______________

This has happened repeatedly (or rather, always), as I said both with the 
'Full' distribution and with the 'Photran feature' installed into an Eclipse 
Europa 3.3.1.1 release (Build M20071023-1652). I add that the corresponding 
option (in the preference menu) is disabled. 
I append herein the lines from the log in which Photran 'explains' what's 
happened:

Any idea of what it could cause it? For what I've been able to understand by 
searching through the archives here, on the list, it would seem that such a 
problem has never been experienced before.

Thank you in advance for your attention. Any suggestion will be welcome...
