If you are seeing random crashes of the GUI or core engine ...

Many users of Process Lasso have experimented with various system 'optimization' utilities. Many of these make permanent changes to the Windows registry that are supposed to speed up your PC. Note that Process Lasso makes NO changes to your system registry or other system settings.

Anyway, one value that is sometimes changed by inferior utilities is CriticalSectionTimeout. This value should NOT be decreased on a whim. This can cause exceptions to be raised in multi-threaded applications like Process Lasso that rely on critical sections to protect data from simultaneous access by multiple threads.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\CriticalSectionTimeout

That is one value that should NOT be decreased, and adjusting it isn't going to help your PC performance in any way -- it will just cause crashes if things take too long. If you see seemingly random crashes of the governor or GUI, please check this registry value if you get a chance. Some of these optimization utilities do things they think will help, but their changes actually have dire consequences.

The default value for most Windows NT+ (home and server) variants seems to be 0x278d00 (2592000). In other words, a long time. Sometimes things take a long time. That's why lowering it is dangerous. It isn't that it that the thread gives up on waiting and just tries anyway, the thread actually issues an exception, resulting in what you see as an application crash.

With the next build, a quick test will be performed to make sure this value is correct. This is the danger of running utilities that tweak system registry values.
