This is really a problem due to the 'folded-grouped' tag, which is more complex to be typeset than, say, the standard 'folded' tag. In particular, typesetting is done using a table, which means that the typesetting is not incremental, so it takes much longer for long and complex paragraphs inside the fold.

I recently created new 'ring' ornaments which should (modulo some more work) allow us to design a mostly incremental substitute for the 'folded-grouped' tag.  In the farther future, tables themselves should be made more incremental.

I've just verified that the problem is only with the "folded group" as in the attachment file.

When I change the outer most "Folded Group" to another folded item such as "Folded Plain" there is no such problem. I can type without any problem. best

CPU is locked at %100 during typing in a folded environment when there are several folded  above the cursor. The computer is extremly slow during the typing and there is a lag about about 20 seconds between typing and appearing on the screen.

This is the case almost in my all files.
It is difficult to explain in sentences so I prepared a simple file with directions in it to produce the error. Please check the attached file.
