AIR runtime breaks AS2 flashlog.txt output

Yesterday I installed the AIR runtime to make use of the Adobe Media Player. Now my AS2 Flash applications can’t output to the flashlog.txt file while an AIR application is running.

This definitely didn’t happen when using the Flex Builder 3 plugin to compile AIR apps from Eclipse, before yesterday that worked fine AND my AS2 MTASC apps would still output to the flashlog.txt file.

And (naturally enough I suppose) it’s also affected my standalone Flash 8 and 7 debug players.

Apparently this is a known issue. See this blog post, this bug report at Adobe, and this unhelpful ‘no workaround’ information from Adobe.

Apparently I just need to quit my AIR application, but I was temporarily sidetracked by an AIR application that failed silently before it launched completely and kept the AIR runtime active in the background (but not visible in the Windows Task Manager). So until I restarted the computer my AS2 apps remained mute.

I’m experiencing this on Windows XP SP2 using Eclipse/MTASC and FlashTracer in Firefox, but I understand from the available info that it’s also happening on other platforms.

My mm.cfg file contains…
ErrorReportingEnable=1
TraceOutputFileEnable=1
MaxWarnings=1

If I find a solution I’ll post it here, but if you’re having a similar issue I’d appreciate a comment.
