Am i going wrong somewhere or is this a problem with the new version
Yes, this is a problem with the new 0.10.5 version.

The former version of mergecap created a new output file, or overwrites an already existing one.
While changing the merge stuff to include it into Ethereal's menu and 
Drag-n-Drop, I've made a mistake with the flags used in mergecap opening 
the output file.
It will overwrite an existing file, but won't create a new one (just as 
you've described).
I've checked in fix into CVS for this.
