Hi

I recently updated my System Workbench to OpenSTM32 IDE 1.0.0.201502061747, and since then I get issues when trying to download the target firmware (New>C Project>Ac6 STM32 toolchain>...>Download Target firmare (in Project Firmware Configuration Page).
When Pushing the button it generates a dump due to an NPE.
here it is the excerpt of the stack trace from .log file

ENTRY org.eclipse.ui 4 0 2015-02-09 15:53:51.513

When reverting back to OpenSTM32 IDE 1.0.0.201412041732 the problem does not occur

Do you know if I am doing somehting wrong which creating this annoying NPE?
thanks in advance for your help
