The longer PM has been running, the less new tabs will make PM choke.
This is not new, and has been so since I installed the first v.28, except maybe for one subversion, and this is absolutely not the first time I write about this problem.
Here are some basic info:
Win7 ultimate 32bit on a Dell XPS 420 with Intel Q9450 and 4GB RAM.
I have another very similar desktop that has exactly the same problem.
The desktops have a huge amount of programs installed and they all run perfect.
I have also tried to install other browsers (Iridium and Firefox) for test, and they both run perfect.
Running with extensions disabled does not help.
I also, some subversions ago, made a fresh install without getting rid of the problem.
Here is the requested troubleshooting info:
WhatIsHang will tell me that PM is in an infinite loop.
PM will eat a complete cpu core when running in this loop.
