Runtime Error Window fails to pop up in Flash Player 10.3.181.34 Debug

I've installed the latest debug version of Flash player plugin for Mac OS X. Diagnostic page http://kb2.adobe.com/cps/865/cpsid_86551.html#ostype=m,prob1=fpver confirms that the version of Flash plugin detected is debugger one. I'am also able to debug applications using Flash-builder debugging tools. But no runtime error pop-ups are shown during browsing. Does anyone have the same problem? Does anyone know how to fix this strange behavior?

I've tried to uninstall the player using this application http://fpdownload.macromedia.com/get/flashplayer/current/uninstall_flash_player_osx.dmg and reinstall 开发者_C百科Flash player again, but no luck.

UPD1: I've created additional user account and found out that error pop-ups are displayed successfully when switched to that account. So it's likely user-profile configuration issue.

Check your mm.cfg. Since you're on a mac, it would be in ~ or /Library/Application Support/Macromedia. This key looks like it might cause that behavior: SuppressDebuggerExceptionDialogs=1
