The last few days I've noticed a small weirdness.

I've made some posts and the lines that get near the end of the row seem to force the next line down an extra line, so for example....

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

....would get posted as:

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

aaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

When I go back to edit the code there is no extra blank line. Then when I close the thread and reopen it, the line that was long has now wrapped and so the blank line is filled.

Is this a weird browser thing?
