@coupes, I admit I'm not very technical, but doesn't writing a really long post count
as activity???
@Chainz, I did have it happen that way before, but this time it was only one window and I was clearly logged on.
And as for copy pasting, I used to do that when the forum was slow and I had bad service (cut out after 30 min of use,crazy) but it was a modding thread, I was in a creative "ZONE"

I'd typed quite a bit and I was like "AT LAST I'VE ANSWERED EVERYONES QUESTIONS!!! CLICK SUBMIT BEFORE SOMETHING HAPPENS!!!"
just kinda forgot about wierd stuff happening after submitting.
