Modal windows not frontmost

[PincoG]

Does anyone have any news about this topic?

Thankyou

To confirm, this only happens on Window 7 and with the same EXE, it will only happen once every 50 to 100 times the code runs. If you have TWO modal subwindows on different parts of the screen over the startup full screen window, the frequencey increases. So if NI wants a way to simulate this, make a bunch of small modal windows that all load after the main screen should have appeared.

In our case, this is a very bad problem, as the customers do not have keyboards and they have to turn off the  power...

I have this issue too, and I am using Windows 10. Typically, floating windows appear in reverse order that they are called. Each floating window that is loaded will be on top of any that were loaded prior. Modal windows (are supposed to) take priority over all default windows and floating windows, and their order is always the last called modal should be on top. However, as this is not always happening (model windows keep appearing hidden behind floating windows), I have steered away from using modal windows at all. When I load floating windows, their stackup seems to work reliably. I have at times also implemented a window hiding VI that I like to use so I don't have open windows stacked on other windows as it looks cluttered. I simply change the transparency of the calling window to 100% while I call the other window, then change it to 0% upon its return. For this to work, the windows you want to hide have to be set up this way. 

Then I call this VI (show hide front panel.vi - attached) to hide the calling window, and then show it when he sub-vi exits. As property nodes do not work when an error enters, I wire the error in and error out separately, otherwise things can become unpredictable.

Make sure each calling VI you want hidden has this at the beginning:

and this at the end.

and I implement it this way.

Hope this helps.
