Debugger stopped working - FB4

[martinjconnolly]

Hi,

this morning my debugger stopped working. FB4 stays reponsive after I hit the debug button - it shows a main thread running - but either IE8 or FF5 freeze, showing "not responding" in the title bar. Windows says Flashbuilder.exe is using a constant 10% or so of CPU and lots of disk access. I have tried installing the latest versions of the Flash debugger player (10.3.181.34) but it makes no difference. Just launching the app works perfectly. I'm running Windows 7 Pro 64 bit on a Thinkpad W510 (8gb RAM, two quad-core i7 processors). Has anyone else seen anything like this?

Thanks

Martin

Just found this in the log: one for every time I've tried launching the debugger today. In fact one every 3 milliseconds when I've done that! No wonder the disk light is flashing constantly.... any ideas anyone? Reinstall Flash Builder?

Thanks

Aha! found this entry with some judicious googling: http://www.fingersdancing.net/2008/06/flex-debugger-crashing-eclipse-safari.html

That related to OS X rather than Windows, but I deleted the line starting "PreloadSwf" from my mm.cfg file and the problem is solved!

Aargh, it's stopped again. The rogue line had come back in the mm.cfg file but even after removing it my browser hangs when I try to debug. This needs to get sorted quickly or I'm thinking of ditching Flex for future development.

Flashfirebug extension disabled and now working - forgot I had that installed
