Abaqus script - waitForCompletion() method

Hi everyone,
I have the following doubt. I just created a plugin and now I'm implemeting the launching models for the analysis. There are some simulations and I'm using "waitForCompletion()" method instead queue (I have problems with queue, due to some times the analysis is not launched and it stays always in submited state). The fact is, with "waitForCompletion()" the GUI is blocked and I can't do any thing, like see results or kill the analysis, like when I launch the simulation from GUI.
Does anyone know how to allow interact with abaqus during waitForCompletion? 
Thanks in advance
