I am working on macromedia flex 1.5 & Action Script 2.0, The problem is that I can't focus on the textInput. What happens is that when clicking text input for the first time, it is not selecting, only after a second time, it is selecting & the component gain focus and i am able to type. The Issue is not for Right Mouse click, it is working fine but the problem is for Mouse left Click.
Flex 1.5 is no longer officially supported and it has been a long time since I used it, but IIRC, you provide an MXML url in the browser and the Flex 1.5 server returns HTML content that wraps a SWF.
The current versions of Flex use JS code from the SWFObject project http://code.google.com/p/swfobject/
I believe there is a way to get the returned HTML content to use this SWFObject code, and that may solve your problem. Of course, the better path would be to upgrade to Apache Flex.
