I'm using the Japanese version of AutoCAD LT 2008 and when I use Dtext only Japanese characters display. If I open a new file I can type in English but not in the file my workmate gave me. I paste in English text he wrote (e.g. R0 S0 T0) but I can't paste text from anywhere else. If I type in English nothing shows on screen but when I Ctrl+a, Ctrl+v here it shows what I've typed, but without entering any Japanese text the box will disappear when I double-tap Enter.
I'm still new to AutoCAD but I have checked that QTEXTMODE = 0.
Any ideas other than starting in a new sheet?
