Hi,
I am trying to learn windows api and message handling.

I had seen an example of custom task pnae in outlook and I tried to add
a custom pane in instant search pane. But when I try to click the icon
to expand/ collpase the search pane, it is not expanding / collapsing
properly. It is responding properly only if I switch to some other app
and come back to outlook, or if I debug it (so then also I switch from
outlook to Visual studio to see breakpoints)

I subclasses the window and taking care of WM_SIZE message.
With spy++, when I see the messages, I am getting the WM_SIZE only
after the switching to other app and comeback to outlook.

What message do I need to process or what should I do to make it
expand/ collapse properly with a click on the icon?

Thanks in advance
