Micro 4/3 Odd Problem With My OM-1s

I have an odd problem with both of my OM-1s. I'm not sure what I'm doing to cause it and have found only one way to get back to normal.
Occasionally I somehow set the camera to Manual focus and can't get it to go back to S-AF+M by pushing the L-Fn on the lens or the AF-ON button. The manual focus>autofocus on the lens is fully forward and I'm pretty much always in Aperture Priority. It persists even when I shut the camera off and back on.
The only way I can get back to S-AF+M is to go into the SCP and reset it. Any ideas 1) how I may be setting it to a hard Manual setting, and 2) how to quickly set it back without going into the SCP?
 
I do have an OM-1 and haven't encountered this problem yet. What firmware version are you running? I am running version 1.3.

Edit: I have just checked and found that if you set the camera to MF using the SCP, then the L-Fn button no longer acts as a toggle between MF and S-AF+MF. Is this the problem?

I'm also running version 1.3. I have no idea what causes it to go to MF. If it was accidentally set by hitting the L-Fn button, it should be set back to S-AF+MF by pressing it again. I'm certain it's a combination of button/buttons presses that causes it. Wearing gloves really reduces my sense of touch so may be a 'winter problem'.
I'll try to email OMDS to make them aware of it.
 
From what I have read, the default function of the L-FN button is "AF-stop" (I can only read about it since I have no lens with that button). From your description of the problem, I assume you like that default and have left it set at that.

One suggestion I have is to set it to something else and then set it back to that default, or just deliberately set it to the default yourself (as opposed to just using the default it came with). I guess I am thinking that goosing it like this might get it to working correctly. Seems like it is in some kind of strange limbo. Just an idea.
 
I had something odd happen with an OM-1 today. It had my 12-40 on. Battery level was good and the camera was in Aperture Priority mode.
All the settings froze - aperture, exposure compensation and focus were all frozen, even when I changed to Shutter Priority and turned the camera off/on. I turned the camera off again, popped the battery out for a few seconds and turned the camera back on. Everything was back to normal again and I was able to continue shooting with no further problems.
Does anyone have any idea what might have happened? I suspect that sometimes I accidentally press the AF-ON button while touching other controls but haven't had this particular issue come up. (I've posted this in 'the other mu-43 forum' as well.)

Graham, any computer can "freeze".
All it takes is one wrong bit in a stream of billions of bits per second ...

Frankly, it amazes me that any computer works at all!
And I've been working with them for over 50 years ...

A friend of mine way back, John McGovern, used to work programming the first generation of electronic computers in binary. He had some interesting tales to tell. I wonder what he would have made of my latest PC. It runs at about the same speed as Telecom Australia's fastest mainframe did in the mid-1980s! Yet fits under my desk, and doesn't need a small power station to power it.

I get that occasionally. It usually fixes itself by turning off or removing the lens. There are 11 electrical contacts between the lens and camera. That's a lot. They are held together by mild pressure so as not to wear unduly. A bit of contamination with a slight jolt or twist, could interrupt data flow a millisecond or so which might be enough to cause a glitch. This electro/mechanical interface is a weak point of removable lens cameras but often forgotten. If that is the reason, it doesn't surprise me. What surprises me is that those 11 hard working contacts don't cause more problems.
