The PDF from hell

A little earlier this evening I had the most bizarre computer experience I've had in years.

What with my chronic allergies & hay fever, I'm thinking about giving Breathe Right strips a try.

I went to their web site, and after poking around a few pages, went to print this PDF, which includes a template one is supposed to cut out to use for determining the proper size Breathe Right strip for oneself.

After displaying the PDF, I turned on my printer, then selected the print option in Adobe Reader. That is when the weirdness started:

• The printer did nothing.
• I went to cancel the print job. It would not leave the queue.
• The computer's air circulation fan came on; this normally happens when the CPU is under strain.
• Did a restart of the computer, then before doing anything else tried printing a small text file.
• The printer still would do nothing.
• I opened up the print queue, and the PDF was still there, and still would not cancel out of the queue.
• The air circulation fan again came on in the computer's case.
• Displayed the task manager, selected the Performance tab, and it showed the CPU was running at 100% of capacity. This while no applications were running. HUH?
• Did a complete power down of the system.
• Powered up again and tried printing the small text file again. It printed just fine, and the print queue now showed no sign of the PDF.

So, I have no idea if the PDF or something else was causing the problems, but relieved I seem to have corrected the situation.
