Prevent the AddOns's Dialogs from being inaccessible #69
Description
As I suggested on Forum.
if the user change the screen resolution, or accidentally move the Window to outside the visible area, this screen would be unaccessible…
Check the Window's boundaries and be sure the whole Window is visible when the user show the dialog.
hint: check if the Window is wider or taller than the Screen, and add Scrollbars.
