The ability to run multiple commands from a single line using the ": ;" format is a bug that's been in EQ2 since launch. Since the early macro implementation only contained three macro lines, this bug proliferated as a common way to run multiple commands from a single line, but it was never supported as a standard feature. Beginning a line with a ":" is the shortcut for the "emote" command. This is why you now see an emote line if you try it.
We fixed an unrelated bug that impacted macros created this way. If we had caught this in testing we would have certainly given everyone a heads-up that this change would impact your macros. So for that, I apologize for the inconvenience.
Going forward, you will need to put each command on a separate command step. We've increased the number of steps you can add to a macro from 10 to 24 and this should be available after the next hotfix.
For those of you still using the /useability command in macros, you can get the same functionality by dragging a spell icon to the macro window and creating a spell step. It even supports casting a spell directly on a player.
And no, we still won't add a pause command to macros. Its not our intention for you to be able to press a button and walk away from your computer while the macro system plays your character for you.
