smoother app updating process

Hi All:
Portable Apps is great and the bundled automatic updating is great. One change would make it even greater. That change is to the behavior of the updater when an application, for whatever reason, can't update. What happens then is the update process stops and a pop up screen appears saying "the app can't update because .......". It then asks you to click OK. Why wouldn't I?

What would be better would be to have the update complete itself and then have the popup or popups appear at the end telling you to check back later or whatever else the team thinks is important. When the update stops it just sits there, sometimes for a long time if I am off doing something else, The automatic update seems to be a set it and forget it mode, so why freeze in the middle?
all the best
