I have a mtext that has propagated in numerous files that has the following problems:
1. at click it is selected very slowly
2. at edit (double-click) it's an even longer wait
3. tedit works perfectly
What I noticed that along with the text, comes a million text styles that cannot be purged/deleted/lisped out of the drawing.
I'm attaching a clean file, only with the text copied in it. Try it, try copying the text in a clean file of your own, same error.
It's a 2013 dwg (3.5mb, with only just one word in it)
