I tried your sample but as it looks good from a first point of view it makes problems in details.

There is massive flickering (redraw effect) on the title bar.
An this seems to conflict with other RadFroms too.

Launch two times the "First Look" sample.
Move the mouse a bit over the three button (mini, maxi, close).
Watch that sometimes the whole title bar flicker - sometimes only the buttons.
And watch also that this flickering also occures on the first started instace of the sample.

You can also do this with the mdi sample.
And also mixed through SDI (FirstLook) and mdi.
Launch First look and next MDI.
Now move the mouse (a bit fast) over the three buttons of the SDI.
Whatch that the "sometimes flicker" ond MDI changes to "a lot of flickering".

While writing this post I have an instance of MDI open on a second screen.
It makes me real nervous to see this "periodicly flickering".

Hi Manfred,

Thank you for sending us so detailed description of the problem.
We are developing NC area double buffering which will hopefully be ready for Q2 2008. Unfortunately we couldn't make it for the Q1 2008 SP1. We believe it will solve such flickering issues.

Please, let us know if we can be of further assistance.
