Scrollbar may disappear in Program window content pane when editing package specification only

I am viewing/editing for instance a package header in Program window. The content pane is visible with a horisontal scrollbar because some of the method names are too long to be displayed in full length.

When I (by habbit) hit Ctrl-H (shortcut to go to next tab page, i.e. shift between program specification and program body) to view the body, the scrollbar disappears, but the content of the pane is the same, now with the result that I can not scroll to se the full method name. When I for instance hit Ctrl-H again or make the pane a little wider or narrower, the scrollbar re-appears.

Not a big problem, but the missing scrollbar indicates that the content pane has the wrong focus and this sometimes causes a run-time error. I have not been able to reproduce this at will, though.
