some Excel files crash using SV 11.1.2.1.

Dear All,

We migrate HFM from 11.1.1.2. to 11.1.2.1. end of November.

Most of our clients run OS: WIN7 64bit and MS Excel 2007 as also SV 11.1.2.1.

We have some Excel files with SV formulas which crash when open the file.

We didn't understand why! Is there someone else who have the same problems?

The files are not so big and also don't have too much SV formulas.

Is there someone who can explain what happens inside the MS Excel when opening the file.

We found some hidden objects created by HFM. Is there anything else?

We don't understand why some files work without any problems and some files crash.
