I run Komodo on a dual-core Windows machine. Occasionally after running a Perl program, either inside the debugger or outside, Komodo will freeze up. This seems to happen whether the CPU is Athlon or Pentium, it doesn't seem to matter.
The key is to open the task manager, select the komodo.exe process, right-click
it using the "set affinity" function.
Remove the checkmark from all but one CPU and komodo will work fine.
Thanks to community contributor JTa for working this out.
