I got it figured out. At least for simplified case. I got a question:
tagLISTVIEW_INFO is our structure or it's MS defined one? If former, I can add
few more variables to it : maxHight and maxWidth - to track dimensions of ListView.
And update it every time on inserts and refreshes.

It's mach smaller than that. I had just 10-20 items. I might try with something
less sophisticated than ACDSee. Somewhere I have explorer like program written in
Delphi. Should be perfect for this.

So far it reacts when size get's too small to fit right most column of icons. But
nothing when size gets bigger enough for one more column. I will try to get some
meaningful logs out of it.

Yes missing names are always the same one. One more interesting fact: if directory
missing name - all files in it don't have them neither.
