When selecting rows in a grid the gradient on previously selected row changes to vertical instead of horizontal. Seems to do this randomly, my demo shows one grid working, the others not. I can't work out what combination of settings causes it.
Also may be related to previous issue colour issue I reported. When AutoThemeAdapt is turned on and Office 2003 blue is selected the selected row font colour has changed from black to white in a recent update. White is almost unreadable.
Will post a demo to support.
