I have a problem where when I am annotating drawings in MTEXT where character do not register as I type them. This seems to be most commonly, but not exclusively, after a space (i.e first letter of a new word) and is especially the case when I am typing quickly. This problem does not present in any other program or even in the command line within AutoCAD. Only in MTEXT.

As an example, a note such as ...

"Hardwood decking over supporting structure to match chalets. Structure to Eng's detail."

Will type as ...

"Hardwood ecking ver supporting tructure o match halets. Structure o Eng's etial." (This was typed in MTEXT as an example).

It is very annoying. I am using AutoCAD for Mac 2015 and have reinstalled it twice to no avail.

Appreciate any suggestions.
