* Open a document that is several screens long. * Scroll down to somewhere near the bottom. * Open the preferences dialog and alter the Zoom% In Look&Feel->Screen_Fonts. * Press Apply on the Preferences dialog.
The BufferView is redrawn as the top of the document, although the scroll bar remains wehere it should be, near the bottom of the document. Touching this scrollbar will cause the screen to be redrawn correctly. This also happens with (an admittedly quite old) lyx 1.2.1cvs, although interestingly pressing Apply will cause not only the top of the document to be drawn in the BufferView, but the scrollbar to move to the top of the document too. So maybe this is a progress report ;-) Angus
