Anyone having problems getting presets or any other drop-down menu items to show, what OS are you using? I got an email report of such problems from someone running Win2k, and Evil Ryu sees this issue on Win98, so I installed VirtualPC and loaded Win2000 onto it to see if I could reproduce it.
What I found:
Yes only one item shows when you click the drop-down menu, but there are small scroll arrows which allow you to scroll through the items. Also, I found that I could highlight the current menu item and the scroll through the other items using the wheel on my mouse.
So, if it appears that those menus arent working, please check for the scroll arrows.
As for copy/pasting vs. other methods of getting presets into the preset folder, I don't see how that could matter. A file is a file, regardless of how it got to the preset folder.
