Closing the DXLab applications might free up enough CPU to allow your

The next time that happens to you try the following:
1) Open task manager (since the machine is unresponsive that might take

3) Click on the CPU heading once or twice to sort the list in descending
order by CPU usage.
4) See what process is chewing up most of your CPU
It might be task manager itself but we know that's overloaded so look
for the next one down the list. Chances are it will be something that
you don't know why it's there or what it's doing. There is a good chance
that it is part of your anti malware program that has become confused
and is beating up your machine. Search the Internet for a solution. You
are undoubtedly not the only one who has had the same problem and there
is a good chance you'll find a solution.
I think you are misunderstanding, I probably wasn't clear in my original post. The machine is not at all unresponsive in this case, task switching works instantaneously as normal but the switch just cycles around the windows of one of the DXLab applications that has two windows open. For example Commander or DXView. Also if it helps anyone diagnose this, it tries to switch to another task but seems to get rapidly switched back automatically to the original DXLab application. So for example I might see a flash of Spot Collector getting the focus, but it almost instantly jumps back to the application it is stuck on.

Subject: [dxlab] DXLab Sometimes Breaks Windows Task Switching
I notice that DXLab applications sort themselves in the active task list so
that Alt+TAB always goes to the next window for the application that has the
focus. I am finding that on a busy XP SP3 system sometimes this breaks the
system Alt+TAB task switching and I get stuck with only the windows of one
of the DXLab applications and cannot Alt+TAB to any other task. Also
sometimes the problem is even worse where the task bar itself becomes broken
and clicking items for tasks doesn't work. The problem has, so far, been
resolved by killing the active task and restarting it.
the Windows task list; the "sorting" you mention above is accomplished by
DXLab applications play no active role in determining their position on
Windows. If Alt+TAB is not functioning correctly on your system, that's most
likely due to a defect in Windows, perhaps exposed by a shortfall in needed
