Occasionally in cases where you've got multiple tabs in a browser and underneath a tab is a certain link (not just any link), it changes a mouse cursor into a pointer (see the screenshot).

I found this while moving around Google Analytics. Left link block there seems to bring that issue up nicely.

Deleting preferences seems to resolve the weirdness

Comment 3 Ain Tohvri 2007-10-31 04:55:04 PDT

The issue is there for the latest nightly

Page renders through the tabs

You can see the Analytics Site Usage area there (Flash) that follows the cursor movement on tabs.

It only happens if the particular Flash area is behind the tabs.

Deleting the preference lists for both Safari and WebKit didn't make any difference

This sound very familiar.  Does it happen when the Flash content is behind a vertical or horizontal scrollbar as well?

Actually, Flash is able to grab the mouse pointer above any of the following Safari chrome:

- vertical scroll bar
- horizontal scroll bar
- status bar (must be turned on)
- resize thumb (lower right-hand corner of the window)
- tab bar
- bookmarks bar (only the bottom half of its height)

You may need to change the height of the <div> elements and resize your browser window to make certain Safari chrome elements render "over" the Flash content, but the way this Flash ad works, it hides the mouse pointer, causing very odd behavior.

Not sure if this bug is in Safari or WebKit.  May be a combination of both (since WebKit draws the scroll bars, but Safari draws the other elements).

Looks like the issue has been addressed in Safari 4.0.4.

It works for me on the latest nightly, version 4.0.4 (6531.21.10, r53677). Please confirm.

I concur that this has been fixed in Safari 4.0.4.

Actually I think this was fixed by Flash 10 rather than Safari 4.0.4.
