I was very glad when the 7z support appeared in WIP, enjoyed using it in cmpro 3.116a but now I've got some problems in comressor options. This is what I'm trying to make work:

Executable - C:\Program Files\7-Zip\7z.exe
Compress - a -y -t7z %1 %2 -mx=9 -ms -mmt

...but it does not work. In previous version the same options in packer.ini were right, I even tied to write them directly into cmpro.ini... Nothing helps. What am I doing wrong?

P.S. Tried using these options directly with command line version of 7-Zip - everything is Ok...

P.P.S. I'm using WinXP Pro SP2
