This happens sometimes on both OSX and WinXP. I will alter a window in some way, but the scroll bars won't change to reflect the new size. So I close the window and reopen, and now the scroll bars are gone. The window is the same size as before (sometimes it grows slightly larger every time-?) , not maximized, but I just can't scroll at all. No kind of resizing or maximizing or restoring will make it so I can scroll to the new info, I have to close the patch completely.
it's normal the bars not to update automatically (have no idea why). to
refresh the screen, it's better to in edit mode click and get out of an
object, whichever one.
but the other errors I never had so far.
