Riamus2, the command "/" is being executed in the first editbox, but is acting on the active editbox (the second editbox) instead of the editbox where the "/" command was input (the first editbox). Of course, these can only be different when using the "/editbox" command.
(To be clear, notice that the "-a" switch with /editbox means it is inputting the text on the active WINDOW, not the active editbox. The "-o" switch is used to reference the second editbox, while otherwise the first editbox is assumed.)
Similarly, typing "/editbox -n windowname /" into a window other than windowname will cause nothing to happen except clearing the contents of the first editbox of windowname.
Again, to be clear, the bug here is that the command "/" does not work as expected when it is input into an editbox that is not the active editbox.
As for the last part of your post, I don't see any issue with "/editbox -n". It does in fact press ENTER in any test I've tried.
