About the "blank modal window".
Its an old Qt bug under MacOS X host since Qt 4.5 (which had a lot of  
changes related to MacOS X look&feel according to Apple HIG).
Its related to window-modality / application-modality handling (which is  
represented by the Mac sheet /  Mac modal window respectively).
I can't explain it fully because I'm not sure why does that happens  
myself, but we had a workaround for it which was accidentally removed  
during one of reworks. Now since the actual issue still present I returned  
workaround in-place again.
Thanks for spotting this issue!

With Best Regards,
