Sim City 4 (+Rush Hour) on Vista 64 bit

The game seems to launch fine after installing and updating with patches. It seems to run fine too.

Except when I save a city it freezes and I need to shut it down through the task manager.

I'm thinking the problem might be with an SC4 ini file that directs where saved cites go but it's not where it should be because of Vista file structures...I could be wrong.

Wondering if anyone has had to deal with this issue and how it was resolved.

Thanks

I seem to have resolved the issue by un-installing and re-installing on the C: drive.

I was wondering about the ini files...Seems I had to create another programs folder on my C drive, and install some games and programs in THIS file because I was told Vista doesnt like files in programs folder re-written to? Case in point, POVRAY, a raytracing program wouldnt run until I was told to install in a newly created file on my C drive so that the INI files could be re-written to as the program runs? So a crash on saving might be a similar situation?
