[Pythoncard-users] Scroll frustration

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hi folks,

In an app that intercepts key presses I want to control the scrolling 
of an HtmlWindow.  The tester below moves the slider in the scroll bar 
but the window content doesn't move unless I click on the slider.  Any 
hints would be appreciated.

I'm running Python 2.3 on Mac OS X

Thanks,
Ken
