Hi Dmitry,

After reading your message I was also going to suggest to check lockscreen. It is the clear indication of the problem and I've seen this effect myself if I forgot to put lockscreen back to off.

But I was out almost all day :)

Glad you found it...

I took the database of that customer and copied it to my computer; tried to open this window and the same weird effect repeats on my computer. I even replaced one of the main tables of this window with an empty one, still the same problem. Reindexed, repacked, the same problem.
