i just upgraded to FB 4.5.1, working on Windows7 64 bit.
Created a new workspace (adobe recommended) and we've several projects & libs for our webapp.
If i'm start debugging, FB says "Launching myWebApp (53%)" an nothing more happens for about 30s up to a minute.
Suddenly the Browser opens (new Tab, testing with FF & IE 32bit) and i can start working / debugging.
There's no error message in FB, i just found a log entry in <workspace-path>/.metadata/.log :
!ENTRY com.adobe.flexbuilder.project 4 43 2011-06-30 08:23:51.283
!MESSAGE Server returned HTTP response code: 403 for URL: http://myserver:8080/myWebApp.html

This behavior doesn't occurs in FB 4 (standalone).
This also occurs, when i create a new workspace (clean).
FB is compiling in a networkshare "\\myserver\share" and launching the above URL (http://myserver:8080/myWebApp.html).
As i wrote, same config with FB 4, it works perfect. And i'm pretty sure, this config also had worked with FB 4.5.1, don't know what could have changed in my config/compontens/settings. Other users of our company have same config, but have no "waiting" when start debugging.
Any idea ? Thx
