Almost 5 stars...

I love this app, have been using it for at least a couple years now, and would have given 5 stars but... Ive noticed within the last couple months that when it synchronizes (which is every few minutes or every time I add or check off an item) the entire screen goes black for a few seconds, instead of just the "pop-down" from the top. This is really starting to annoy me when Im in the grocery store, trying to check off my list and quite often find myself standing there staring at a black screen, waiting for my list to appear again. Please fix!! It never did this before and I dont know why it started now?!
