Changelog
The following changes have been made since the release of the previous version:
- FIX: On systems older than Windows 7, the tool bar chevron popup window could be displayed off-screen.
- FIX: The GetAvailableButton event had problems with the button texts. This issue could not be fixed entirely, but now a simple workaround exists. See the help topic about this event for details.
- FIX: The IToolBar::LoadToolBarStateFromRegistry method did not work properly.
- Fixed a memory leak that occurred during drag’n'drop if Aero drag-images have been used.
