Dear Richard,

In my company, many of us are having the same problem as Dmitriy. CAESAR 6.1.2.200. Considering all your comments:

1) We have checked that all the files and the folders are not "read only".

2) It happens in different computers with different calculation and in different folders.

3) Closing the CAESAR input, the TEMPMAT file is auto-deleted.

Hope you can help us, Thank you,

Pablo
