Hi,
The tabline may flicker when opening a new tab after 7.3.759 on Win32.
How to reproduce:
gvim -u NONE -U NONE
:tabe " Open a new tab. The tabline will appear.
:tabe " Open the third tab. The tabline may flicker.
" (Some extra tabs appear a moment.)
It seems to be caused by TabCtrl_SetCurSel().
Attached patch fixes this.
Regards,
Ken Takata
