Thank you for helping me, I was able to fix the problem after fiddling with the settings on my card. I didn't have this problem when I first installed AL, it just started happening after I updated the drivers for my ATI Radeon Sapphire 3870 PCI E graphics card - I've updated the driver twice in the last 2 weeks. Could you or someone else explain why some objects go invisible and others don't? It doesn't make a lot of sense to me, it seems like if one object is effected then all should be...I'm just curious as to why the same objects are showing up invisible up for more people than just myself.
Thanks again for the help,
Julie
Edit: I've solved my problem. It wasn't any of the Catalyst settings. Something changed after a driver update, I cannot have (in game) smooth edges on at all or I lose the transparency of objects. I have every setting maxed in the Catalyst center, tried every setting and screen resolution - it all comes down to using the smooth settings in game. From now on I'll be looking at jaggy edges, unless another driver update comes along and fixes it...or I gather up enough cash to buy another system and graphics card and that isn't likely to happen anytime soon.
Thanks again Simsample
