I noticed that the “Text” controls i.e. TextInput, TextArea and RichTextEditor are behaving differently capturing Key strokes. This is happening only on Firefox 2.x on Mac OSx 10.4 where repeated keystrokes are not getting captured and holding down the key does not print the character on the screen.
Now that I an over some of the simple things in Flex and started to use this in a real application, I am finding limitations in Flex. Just today, I created my account with Adobe Bug System. While I wait for Adobe to start replying, I am going to use my blog to communicate these to the community and hoping that we can also find a solution.
