This might be an Eclips vs a FlexBuilder issue, but I have
noticed that my keyboard cursor sometimes does not show when I
click with the mouse on the current/highlighted line to insert
text. The cursor is there - if I type then my text will show up
where my cursor should be, but I just can't see it. It's not a huge
problem, but a small annoyance.
Just throwing this out there and hoping it can be fixed,
maybe in a future update?
