PCManFM-Mod 1.2.4 issues

[coreplayer2]

This is a great File manager, might be a little large for many applications, but quite suitable where space is not an issue. 

I've always been curious how we assign lxde-icon-theme to PCManFM-Mod.?  There doesn't appear to be a config file which specifies which icon theme to use afaik.

While I'm not sure exactly how I managed to fix this, but after deleting all files in home & opt directories, I rebooted to a fully functioning PCManFM using ldxe icon theme!!   some corrupted hidden gtk config file no doubt, oh well!!

Update!!  I believe I found the answer in a config file named .gtkrc-2.0

Also, 

from the tool menu - selecting "Open Current Folder as Root" results in an error message stating that  "su command not found"  ??!

(this occurred in v1.2.3 also)
