I have an SP3 i7 that I primarily use for lecture capture in a university classroom. When I'm doing this, I commonly will only have open on my computer PowerPoint and Camtasia Recorder. I plus a USB mic in for audio capture and connect via a dongle to the video projector. I did this all last semester without problem. This semester, I have had two recurring problems (one is really just an annoyance). Problem 1 (minor): When I launch PowerPoint to do the slide show, the Windows taskbar at the bottom of the screen stays in the foreground. I have to tell the system to auto-hide the taskbar. I don't have to do this with any other Windows/PowerPoint combination, except for my SP3. Problem 2 (major): This afternoon my SP3 seemed to have a mind of its own. Periodically during the lecture--and it often happened when I was not interacting with the system at all--the video would black out for a couple of seconds (it actually looked more like a dark magenta than black) and then when the video came back the screen display was all screwed up. What should have been being projected full screen was showing in the upper left quadrant of the screen, occupying about 75% of the overall screen. The rest of the screen was showing the PowerPoint workspace (i.e. what is normally not visible when one is in presentation mode.). The only way for me to regain control and ability to ink was to close PowerPoint and reopen it. I had to do this about 10 times in the course of 2 hours. I don't think I've ever been so frustration with my SP3. Continuing the above, when I returned to my office after class I noted that my Camtasia capture of all of this was corrupted. So, not only was my lecture severely impacted, the recording of it was unusable. I used this system all last semester with only the occasional minor hiccup. This semester I've now had 2 instances of the above in 7 days. If this continues, I'm going to have discontinue my use of the SP3. Anyone have any suggestions?
