1st test, release_6.0.0 branch, developer build, Win10

• exceptions present in log
• proper resolution image produced

The exception is coming from unnecessary check in sascalc\calculator\resolution_calculator.py line 1007. removing this check makes the calculation succeed without the errors shown.

Will test with the installer build

Win10 Release build works the same as dev version. I will remove the check and let's see how it works on macos

@wpotrzebowski please test the installer from 2705-resolution-calculator-fails-to-compute-image and see if it still fails to display the image

Humm..., It seems this has been fixed and then forgotten?!! Can we just make a pull request from branch 2705-resolution-calculator-fails-to-compute-image for release 6.0? of course it may need to be cherry picked onto release_6.0.0 at this point?
