VuGen freezes when launching an Ajax TruClient for Firefox script in load mode

Hello,

I recorded a script with the protocol Ajax TruClient for Firefox protocol and when I try to launch it in load mode, VuGen freezes and any action is possible.

The only way is to stop the program throught the task manager. When I click on close the program button, a popup relative to VuGen appears. The following message is displayed : "Do you want to stop debugging ?" If I answer "Yes" nothing happens and same thing to "No"...

VuGen version is 11.52 Patch 1 (Build 5113) and is installed on a Windowd 7 SP1 64 bits operating system.

Could you help me on that ?

Thanks for your help.
