I had a new web site that was working just fine except for a seach box in my left navigation panel. Using Firefox there was no cursor showing in the text input box. The box accepted input, it just wasn't showing a cursor. Using Internet Explorer it was working just fine.

I found thru a web search relating to this problem, that it was being called a Firefox bug and there were several posts recommending changing the 'overflow:' property on the enclosing 'div' or add a 'div' around the input box with 'overflow: auto;'. I tried 4 or 5 of the recommendations with no success. For me the correct solution was the following:

All 'divs' need to be used in the order of their 'z-index'. So, if you look at a view of your page source, the first 'div' you see must have the lowest 'z-index' and so on until the last 'div' with the highest 'z-index'. It matters not whether they are nested or stacked or if they overlap.

Kind of an odd fix but I'm happy to have it working.
