Hi all, after having reported a few problems of getting IMON to work on 9x based systems and after gpdev confirmed this issue to me (Thanks!) and encouraged me to mess some more with the registry settings ( once again thanks, gpdev), I came up with a fix to make IMON work on 9x based systems. But beware: This includes manually editing you registry, so please don't blame me if anything goes wrong. You can probably damage you whole internet access. This is only for experienced users. Now that the warning is said, here we go: After you installed and enabled IMON go to the following registry key in regedit: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\WinSock2\Parameters\Protocol_Catalog9\Catalog_Entries You should see a list of numbered providers as subkeys. Each subkey contains a binary PackedCatalogItem value. Open this value and (only) if it starts with imon.dll change this setting to c:\windows\system\imon.dll. Please make sure that the PackedCatalogItem does not increase in length (last full line should be 0370) and that after the c:\windows\system\imon.dll entry you have at least one plain zero. After this reboot and enjoy. IMON scans your emails and internet access won't crash. So: This IS an IMON install bug and I would really like to see it fixed because I am not sure if everybody on a 9x system would like to do this manually. Btw, I checked this issue on ME and it seems to occur there, too. If you have any questions about this fix, pm me. And again: You do that on your own risk! Regards, Karl.
