Hi again,
Some updates:
I've managed to catch the problem again. Practically, the IDE stops at linking phase.
It shows the message in attachment. I leave it more than 12h and it didn't finished.
I've looked in Windows task manager and everything seems to be OK. Plenty of memory available and the processors (I have a dual-core) are not used.
Once, I think I've read something on this forum related with a long time linking due to a very big *.xml file. I'm not sure ... i will search.
Any other ideas will be appreciated.
Thanks.
