This thread in PC Beta http://community.logos.com/forums/t/48540.aspx (reposted from a thread by SteveF in the private beta FSB forum) contains a write-up of a bug in the Community Notes pane in L4 Beta 6:
Deleting the reply post to a community note and immediately trying to reply again (which may be a typical workaround to stand in for a missing edit feature) will generate a bouncing edit box.
Now I just checked and can replicate the same behaviour in biblia.com - using the Chrome browser and using IE 8 as well.
Maybe interesting for the developers: in IE 8, before the bouncing starts, it asks me to confirm an error message sent from the website: "Out of memory in line 23"
So far, only SteveF, using Win 7 Pro 64 bit and myself, using Win 7 Home Premium 32 bit have posted about seeing this.
Anyone with another Win Version and/or other browser seeing this as well?
