As a quick fix I made the following change to the function Mint_SI_IO() in script.js (line 23):
Original:
if (link.href && !Mint_SI_IO_isLocal(link.href)
&& link.href.indexOf('javascript:')==-1)
With my fix applied (additional condition):
if (link.href && !Mint_SI_IO_isLocal(link.href)
&& link.href.indexOf('javascript:')==-1
&& link.href.indexOf('/mint/pepper/')==-1)
Ideally I would have changed the regex in Mint_SI_IO_isLocal(), but this seemed to me more risky, since I would have to dive into the regex.
The fix seems to work fine, but be aware, that this is NOT supported by Shaun and everybody using that fix is doing so on his/her own risk!
