I run into this all the time in PowerPoint, and it's a pain in the... wrist.
A co-worker and I discovered this a few years ago back in PowerPoint XP.
When we couldn't figure out how to turn it off, the co-worker called
Microsoft because we figured there must be a way to do so and we just weren't
seeing it. The tech couldn't find it and when he went to consult someone else
behind the curtain, he came back astonished to find that there is no way to
disable the change in formatting.
The rationale behind this involves the presumption of a template being used
in PowerPoint. If you're not, the copied text is assumed to belong into the
default template. So if you copied 12 pt. Courier source and then pasted it
elsewhere it would show up in whatever font and size that Powerpoint felt you
ought to be using based on this mysterious default template.
It was also suggested that you got this when you copied something from an
earlier version of PowerPoint into a newer one, and that text from within the
document wouldn't change. I've noticed that's not always the case. I have
Excel charts that I've pasted as Enhanced Windows Metafiles, ungrouped and
converted into drawing objects, and if I need to cut and paste the text it
will do this silly format-change as well. That's copying text from within a
PPT 03 file and pasting it back into a file of the same format.
I have wasted more time and clicks correcting this so-called "feature" than
I care to recall. Considering the bulk of the cut-paste that I do is correct
problems created when converting the chart from one MS app into an MS drawing
object within another MS app... well, it makes me wonder why MS tries to
"help" me so much. In assuming that they know what I want to do, they're
actually creating more work and a higher probablility of carpal tunnel
syndrome in my mouse hand.
The fact that Office 2003 didn't do away with this "feature" that nobody
wants and even their own techs are amazed cannot be switched off is a sign
that the feedback process needs work. As near as I can tell, nobody asked for
this "feature." Nobody likes it, and everyone who's seen it wants to turn it
off. When you buy the new version of the software and something like this is
still in it... it makes me wonder why I bother upgrading.
/rant.
My input would obviously be to either do away with this "feature" altogether
or at least give me the option of going back to the old way. Statistically,
I'm more likely to keep the format of what I copied than I am to change it.
If I copied 12 pt. Courier, I probably want 12 pt. Courer. Don't change it on
me. I'll change it if I need to.
