When using big FIR tables I often find the SigmaStudio runs out of memory and stops working. I've raised this issue already in another discussion with pa_py but it's not solved yet so I try to raise a bug report instead.
When closing the FIR table editor window I get error messages after several minutes, two examples attached. A few times I've managed to load the table but it took about 6 minutes. I also attach a FIR table example for info.
I'm using SigmaStudio 3.12.3 on a Win7 PC with 4GB memory.
