Adobe Indesign Frame converted to text frame righ aligns...aaagh!

I have spent the last couple of days trying to get a colleague's build of Indesign cc 2014 to behave.

She is in the habit of creating a rectangle frame and then immediately converting it to a text frame. At which point the text in the converted frame will be right aligned and adobe arabic.

I have gone through every preference I can find, a lot of which were indeed infected with the arabic language, right aligned issue. I did this without a document open, closed and opened Indesign many, many times.

...and it worked. For everything EXCEPT when she creates a retangle frame and then converts it into a text frame.

I am ready to scream. Solve this one and I will accept you as the Messiah.
