Hello,
I'm using Avast! Free Antivirus v6.0.1367 Virus Definition 1111205-0.
I had trouble debugging applications between any browser with Zend Toolbar installed and Zend Studio 8.0 for PHP. :'(
The problem is that the debugging functions are not working as expected between the browser and Zend Studio (all connections are to & from localhost, no internet web site is involved).
Disabling the Web Shield of Avast! solved the problem.
Every time I switch the Web Shield ON the problem arises again.
This message is FYI to aid debug the problem.
Until I'll not see a fix for this problem to the Avast! engine, I'll leave the Web Shield module switched OFF.
Greetings,
Stefano Coletta
