[PD] vista & win7 support ?

[rene beekman]

we're having problems running pd-extended 0.41.4 on vista & windows7
problems seem to be related to several particular objects or patches
one example is the select-help patch. opening the help patch either via the desktop, or from within pd via the browser or via the context menu's 'help' option results in windows closing pd

the application error log on one particular machine shows this:

Faulting application pd.exe, version 0.0.0.0, time stamp 0x4a277929, faulting module ntdll.dll, version 6.0.6002.18005, time stamp 0x49e03821, exception code 0xc0000005, fault offset 0x00041f3c, process id 0x1534, application start time 0x01caad6a4a506d60.

on the windows7 machine, it is the same library that is marked as "faulting module", only it's a 6.1 version 

is this a known bug?
any workarounds?

thanks in advance
