pdfcreator 1.2.3 reliably hangs, using all cpu and increasing use of pool memory on win xp sp3, until it eventually runs out of memory, when printing (i.e. producing pdf) from firefox 3.6.27 from certain web pages. One example is: http://www.nytimes.com/2012/02/21/health/aging-of-eyes-is-blamed-in-circ...
The point at which it hangs is after clicking "save" from the pdfcreator control window, and before any animation indicating that it is working, and before it asks for location to save to.
This problem has existed for numerous versions already, but it is hard to predict which print jobs will fail.
Bullzip 7.1.1218 reliably never has any problems creating pdf from the same web pages, for example.
The same problem frequently occurs printing Thunderbird email messages. Again, no problem with bullzip.
