Every once in a while you will experience something "impossible" in computing...
A few years back, I was running win2k on a 486, using it as my web/ICQ/IRC machine. While listening to net radio, ICQ and IE both generated a critical error and brought up that generic win2k close program box.
I chose to ignore it, because the net radio was still working in the background. I also didn't close it because ICQ was receiving a file, in hopes that it wouldn't totally die until the file was finished. After a few minutes I began to wonder... I moved the error dialog boxes down into the lower right hand corner so that only a few pixels were visible.
For about four more days afterwards, I would get a new "ILLEGAL OPERATION" dialog boxes that I would just move aside. I also got a few others such as "This program has generated errors and must be shut down..." Again I chose to ignore them.
I left those error boxes down in that corner, with those programs working just fine, for three months. When I finally decided to shut down - Those error boxes had dissapeared. They were nowhere to be found, and all the programs that had "Crashed" were still working just fine, like nothing had ever happened.
