Focus() call on a select tag seems to be causing problems

Question

I have a reasonably complicated web site with dynamically created, absolutely positioned, overlapping divs with form elements contained within them.
Starting with Firefox 4 and in Firefox 5, clicking on a dropdown list (<select>) tag can cause fragments of text from some of the "bottom" (i.e. not visible) divs to appear within the "top" (i.e. visible) div.
I can make this problem go away by setting the onmousedown handler (not previously set) for the select tag to a dummy event handler which terminates the event. I can force it to happen again either by allowing the event to bubble up or by explicitly calling .focus(). Also, causing any part of the screen to refresh (such as writing to the DOM) will cause the fragments of text to disappear and the problem does not then reoccur with the given <select> tag.
This issue does not arise in IE 8 / 9, Opera 10 / 11 or Chrome.
Is this a known issue? If it is the .focus() call which is causing the problem and given that that is native code, is there a workaround other than what I have done?

Took a look at the SQL Navigator. The "DB Navigator" (the navigation tree on the left with all the DB objects in it) shows the right precision and scale of every column, whereas the "columns" tab that appears when you >double click the view in the DB navigator always shows "number(0,0)". So I consider this a bug of SQL Navigator, but don´t believe it has anything to do with your problem.Yup, you're absolitely right. Not impreseed with SQL navigator!!!
Just a thought: Could it be that some restrictions concerning the db user (dunno, perhaps even FGAC?) prevents that specific data to be shown? Do you connect in SQL Navigator as the same user as with the other >applications?Nice idea but I'm using the same user account.
My background is in SQL Server (don't hold it against me :) ) and that has a tool called Profiler than enables one to capture the query being executed against the database engine. Does Oracle have anything similar? It might be useful to test whether the driver does something funky to the query that might manifest itself in what I'm seeing!
