When i use more than one browserframe at a time maximized (subpages opened in a new window, for instance) i frequently experience problems. The problem is that when i switch frames, the subpage often doesn't get redrawn, and it will only show a (seemingly) blank page. Then when i scroll the page (blindly, the scrollbar disappears too) the content will return in places that have changed due to the scrolling. For instance, the up/down buttons in the scrollbar won't return until i've mouse-overed them. This only seems to happen with newly opened frames. The first frame the browser opens at startup keeps drawing correctly.

Marking as dupe but pretty sure this is fixed in the latest builds. *** This bug has been marked as a duplicate of 66034 ***

Verified dup.
