--- Comment #6 from Dmitry Timoshkov dmitry@baikal.ru --- (In reply to Anastasius Focht from comment #4)
The main user interface is actually there - just invisible.
Using some Spy++ tool one can see the whole window/control hierarchy. The top-most window has 'WS_EX_LAYERED' extended style set.
Anastasius, how have you managed to skip the initial login dialog?
It would be interesting to know exact API sequence the app does which is supposed to make main window visible. Is it SetWindowPos(SWP_SHOWWINDOW), ShowWindow(SW_xxx), SetWindowLong(WS_VISIBLE) or something else?
It might also be a side affect of WS_EX_COMPOSITED (0x02000000).
Anyway this needs some tests.
