Macro text changing

[Sabin76]

I have a macro set up for my pet to assist my target like this:

Line 1: /assist
Line 2: /attack off
Line 3: /attack off
Line 4: /pet attack

The last two times I've logged in, I noticed that there was a space after the "attack" in the last line. I've fixed it each time, but it seems that when I log out, the space returns. Not sure WHY it would decide to add spaces to my macro lines when logging... and I guess it's relatively harmless provided I remember to correct it every time, but it certainly shouldn't be doing that.
