Flash CS5 not stopping at breakpoints

This probl开发者_如何学编程em has been bothering me for four days now with no glimpse of a solution. All of a sudden when I'm working on Flash CS5 it stopped stopping at breakpoints I set when I'm debugging. So far I have tried the following,

• Reinstalling Flash.
• Uninstall and reinstalling Flash.
• Remove the whole adobe suite and reinstalling.
• Reinstalling windows.(Formatted HD, sounds ridiculous I know :) Still, the problem prevails. I have been working with this copy of Flash CS5 for about four months with no problems at all.)
• Tried connecting to the debugger or the profiler through localhost and the IP 127.0.0.1.
• Unistalled Flash player and reinstalled.
• Installed the latest Flash player.

All leading to dead ends!

When I installed the same copy on one of colleague's PC, IT WORKS just fine!

Here is a video of the bug I recorded a few days ago. http://www.youtube.com/watch?v=n4LdQ8wRECY

I had a similar problem with the debugger. Maybe they're somehow related.

For me, the debugger was stopping at the break points. However, it was NOT showing the yellow arrow, so I could not tell where the code flow was when stepping forward.

Eventually, one of the tech support guys discovered that the problem was somehow linked to my PC user profile. He created a new user profile for me and then copied all of my other "stuff" over.

This worked well... for three days. However, this happened to me AGAIN today! I was debugging just fine. I made a change, fired up the debugger, and lost my arrows. I tried rebooting, but they're still gone.

I HATE CS5. It's a total piece of crap!

I know this is an old question, but it's a problem I recently ran into as well and found there's a simple solution to it.

Go to Window > Debug and open the Debug panel. This panel has to be opened at some point during your Flash session in order to display when the debugger runs. When you create a new project it's opened by default, but on subsequent openings of Flash it doesn't always open automatically, and needs to be opened manually. This will reinstate breakpoints and stepping.
