Please be aware I did read this posting.


My problem is the following:
I'm using Plus windows with no titlebar, using XML like this:

code:

---

    <Window Id="WndMain" Version="1">
        <Attributes>
            <ShowInTaskbar>true</ShowInTaskbar>
            <Caption>Chatflash.nl Video Search</Caption>
            <SetForeground>true</SetForeground>
        </Attributes>
        <TitleBar>
            <AllowMinimize>false</AllowMinimize>
            <AllowClose>false</AllowClose>
        </TitleBar>
        <Position Width="310" Height="370"/>
<!-- etc, Elements, Controls, /Window -->

---

The window shows fine, looks like this:



Then, at some point later, I'm using JS code to change the title displayed in the system taskbar, using JS like this:

code:

---

Interop.Call("user32", "SetWindowTextW", wndMain.Handle, strSomeNewTitle);

---

The taskbar button changes accordingly:


But the displayed window gets corrupt.



And all this on
Windows XP Service Pack 2 (5.1.2600)
Windows Live Messenger 8.5.1018
Messenger Plus! Live 4.50.0.312.

Any reason, solution in sight?
Thanks for your help,
