[RESOLVED] Multiline textbox in Mozilla/Firefox

[homer13j]

I have a large multiline textbox that gets reduced in size considerably by Firefox. I have tried

txtDscps.Attributes.Add("height", "500px")

And

Dim h As New System.Web.UI.WebControls.Unit(500)
txtDscps.Height = h

And I Firefox still only displays the textbox three lines in height.

I know, I know. "Just use IE instead." Problem is, the previous programmer here put a browser check in every single page he wrote on our intranet that prevents it from being displayed in IE for no better reason than an intense hatred of all things Microsoft. On of my first instructions was to get these pages to work with IE, but until I remove the browser checks from every single page any new pages I create have to work with Firefox.

So how do I get Firefox to give me a large enough text box?
