Hi Hans,

Thanks a lot for having fixed the issue I was reporting.

Unfortunately I found another issue related to placeformula and alignment in math mode. 
In the following example the use of \startalign in a \placeformula triggers a weird behavior in the sense that the following instance of \startformula gets also a number, even though one does not issue a \placeformula command. Moreover the number is placed incorrectly.
In the resulting PDF I am attaching, please look at the numbers (4) and (8) placed incorrectly (and they are not wanted neither…).
When one removes the \placeformula command, the result is correct.

Best regards: OK
