I installed FB4 this morning on OS X 10.6 and have not been able to use the debugger mode since.
Whenever I start a debug session the launcher always stops at 57% waiting to connect to debugger.
I have tried uninstalled the Flash Player, restarting and installing the player again.
I have been using the flashplayer_10_plugin_debug_ub.dmg file from Adobe's site. It is dated 26 Feb 2010.
This is so annoying and has seriously soured my go with the new version. I had such high expectations too.
Anybody else had a similar problem?
Just to add that running in debug mode on Flex Builder 3 works fine. So I think it's something to do with FB4.
Okay, rather embarrassingly, the fault was in the HTML template for the page. The Flash debugger works fine when the flash file actually runs!
My fault, and everything suddenly looks really cool again.
