Same question here... I was told that it happens when you start IL2 with UI, then click somewhere else. The problem is: I desperately avoid clicking anywhere else during this period and still it happens, at about 50% of all cases. I would also be evry interested in any information in how to get rid of this annoying and - from my point of view - absolutely needless nuisance.

[I would bet it's some kind of "MS Windows does this to you" thing...]
