[wxPython] System default web browser / wxConfig

Hello,

can anybody help me with wxConfig and the Windows registry ? I want to get the pathname of the system's default web browser. The Key HKEY_CLASSES_ROOT contains all registered file types, and the filetype htmlfile contains the pathname of the default web browser.

But wxConfig allways locates me underneath the HKEY_CURRENT_USER/Software node, without the possibility to get on an upper level ( ../ doesn't work -> security problem ? ):

conf = wxConfig ('MyAppName')
conf.SetPath ("/../../../HKEY_CLASSES_ROOT/htmlfile/shell/opennew/")
browser = conf.Read ("command")

I hope anybody has encountered a similar problem before.

Thanks,

Chris
