Code Issues Projects Releases Packages Wiki Activity

- Fix positioning of text in buttons.

Browse source 
- Fix nButtonHeight so that it is not zero in some cases
- Support TBSTYLE_TRANSPARENT.
- Fix handling in WM_ERASEBKGND so that the default erase occurs
  between notifies.
- Fix WM_NCCREATE processing to issue proper WM_STYLECHANGING (via
  SetWindowLong) and document the issues.
