Thanks for sample...

 

Problem 1. Thanks checking this.

 

Problem 2.  Project use standard CHeaderCtrl without our controls. So think you have send it to support of Microsoft. it defentelly looks like bug in ComCtrl32 Header control.

 

I have attached a very small project based on the SkinMDISample application.

 

This app has a Header control at the top of a view. It exhibits two problems, both related to Drag and Drop.

 

Problem 1, click on one of the Header Items and drag it left or right to rearrange the headers. As it appears over the boundry between two other headers, that boundry is supposed to change colors. When I used exactly this code on an MFC app (with out Code Jock) it works properly.

 

Problem 2, click in one of the Header items and then immediately drag straight down. Then move the mouse (with the button still down) left or right a few items worth and then slide it back onto the Header Ctl. Then move it Left or Right and watch what it does. It does some kind of really weird tracking offset.
