I used to do craps with the Grabber distribution. Sometimes you could not use the soft at all...
It should be fixed now. The version seems to be quite "stable".

What's new in Grabber ?

• Session ID / Server time retrieval
• A better JavaScript/HTML parser
• Some basic stuffs for the Hybrid Tool (I don't think I will support the regular expression soon even if it's almost in the code... I need to make my mind about the Source Code Scanner: I will look closer on PHP-Sat and other Stratego/XT based languages support)
• A JavaScript quality checker plugin (using JavaScript Lint)
