Hi Don, Yes, Dr.Watson can bring a system to its knees, to the point where it becomes unresponsive (freeze). One of the ways to regain control is to bring up TaskManager and terminate the Dr Watson process.Tip:Set priority of TaskManager to "High" - at least you'll stand a fair chance for it to run.After that, disable Dr Watson if you don't want anymore of this nonsense. Below are some more links from my "arsenal";) about Dr Watson: * Please Note: In all links and descriptions note there is a difference between Drwatson.exe and Drwtsn32.exe Sometimes both can be found even on XP (Result of upgrading) Description of the Dr. Watson for Windows (Drwtsn32.exe) Tool http://support.microsoft.com/kb/308538 Some excerpts *If a program error occurs, Dr. Watson for Windows starts automatically. *By default, the log file created by Dr. Watson is named Drwtsn32.log and is saved in the following location: drive:\Documents and Settings\All Users.WINNT\Application Data\Microsoft\Dr Watson *Note Drwatson.exe is an older program error debugger that was included with earlier versions of Windows NT. Microsoft recommends that you use Drwtsn32.exe instead of Drwatson.exe in Windows XP. http://en.wikipedia.org/wiki/Dr._Watson_(debugger) http://www.computerhope.com/software/drwatson.htm http://www.hotcomm.com/FAQ/FAQ_drwatson.asp Lots of info and links here too Very useful site -explore ;) http://www.windowsnetworking.com/kbase/WindowsTips/Windows2000/RegistryTips/RegistryTools/DrWatson.html Regards, Peter E. -------- Original Message -------- Subject: Re: [PCSOFT] Hard drive full From: Don Penlington <[log in to unmask]> To: [log in to unmask] Date: 25-Jan-2009 9:00:56 AM Peter wrote: A lot of people "use" it without even knowing it,because of their settings and wonder about severe slowdowns.>> I never knew that Dr Watson could be a cause of slowdowns. That's another item to add to the list of performance factors I'm sure most people would be unaware of. Thanks for that. Does it really have any useful function these days? I looked at the debugger file but was none the wiser except that I now have a nice rude hi-tech name to call my computer when it goes wrong! Just logging errors doesn't seem to help much as these would be in Event Viewer in any case. Don Penlington "Hold No Punches.."
