I was writing a long reply, two pages long and I got distracted by my students with their opamp circuits. Apparently ether should conduct where a wire goes missing and psychic power turns on instruments when needed
Then the damn post thing timed out and I lost my two pages. Very nice Mr. script, very nice!
I don't know why. I used IE8. It displayed the thing timed out. I spent some time typing and found myself typed too much so next time I'm serious about something I'll use a notepad. Students are distracting ]
I haven't had the timeout problem but often get submits and previews that don't work so I've got into the habit of doing a ^A ^C regularly and ALWAYS before submit or preview in case things go belly up.
I should say though that this is not perculiar to this forum, I do the same everywhere, probably my interweb link, but still good practice I think. I sometimes also use notepad for long posts.
