I am new on a large Flex project, and when I go into design mode on one of the mxml files, I can't select anything. The other views work fine. Is there a lock, or something? Below is what it looks like (black mark just hides brand info). Note that there is a red line near the bottom. It is actually selectable, but it doesn't do anything. If I go to Source mode and select a chunk of code, then back to design mode, it does show it as selected.
This in Flex Builder 3, thanks.
Have you tried using the outline view for selection?
