Some dialog pop up on wrong screen
On Windows OS, in case the user have multiple screens, some dialog does not pop up on the current application screen. If you open LV on one screen, then move it to the other one, some dialog may be displayed on the previous screen.
This was the case with the error console and the python console with PV5.4 bjacquet/paraview@fd68face
This was the case with the export spreadsheet : bjacquet/paraview@462a742d This is reproducible on PV5.6 and PV5.9
This was the case with the calibration dialog (once it has been moved to reaction) !184 (merged)
According to the Qt documentation, the dialog should pop up on the top of the parent. We do not really understand this bug.
