CMFCOutlookbar

I use that class to add a ctreectrl as a tab
Adding items into the tree works fine until there occur any messages to redraw the tab section (resizing, default tooltip displayed etc), which causes the newly added item to be added repeatedly every single mouse move then. If you know how fix this problem, please let me know. Thank you very much.

I think you should override the WM_SIZE event to hand the resizing of TreeCtrl.
