Outsytems 6 + RichWidgets Popup_Editor 

Outsytems 6 + RichWidgets Popup_Editor 

  
I change from outsystems 5.1 to 6.0 and i had a problem with the Popup_Editor and ajax, pressing a button or using checkbox with ajax in the Popup_Editor the popup always make a blink and in the 5.1 works great. After tests i found that if i dont put the WidthPx and HeightPx on the Popup_Editor properties this happen in 6.0 but if i put pixels there doesnt happen. 

Is this a bug? I have alot of Popup_Editors and put the size in all will take some time, i need to check the size for all pages.
