[ish]

The problem is that I need to change transparency in RUNTIME (i.e. not in the initialization script)

I've got the problem with the following application:
The applications shows a beatiful splash on transparent background while loading. Then after initialization and some other internal actions the program
should switch to a standard window mode with a taskbar, buttons, etc. I use that script I described earlier to change the window style. This piece of code
is definitely executed but the window remains transparent.
