Q:

Flex 3 - Equals sign (=) in TextInput control Is displaying as a plus sign (+) in Firefox

When I deploy my Flex application and browse to it in Firefox (3.0.8), typing an equals sign into a TextInput control results in a plus sign.   
In Chrome and IE, an equals sign works as expected.   Also, when I run the Flex project locally in Firefox, the equals sign works properly.   
I have tried deploying the SWF on a different server but the equals symbol is still being converted to a plus sign in Firefox. 
Here is the CSS applied to the TextInput control:
TextInput
{
   color: #333333; 
   fontSharpness:"200"; 
   fontAntiAliasType:"advanced"; 
   fontSize: 12; 
   font-family: Arial, "Hiragino Kaku Gothic Pro", "ヒラギノ角ゴ Pro W3", "ＭＳ Ｐゴシック", sans-serif; 
}

Besides CSS, there have been no other modifications to the control.   Any ideas? 

A:

This is a known issue in Firefox/Flash.  If you disable wmode=transparent, it should work as expected.
