Copying files is absolutely no problem. I can do it in 8 different programming languages myself. I doubt anyone finds that task over whelming . What makes it hard is listening to less than stellar answers and trying to use them to do it. Just the few I read "its in the opera folder". Well unfortunately in PCs it has 4 different folders. Appdata low and roaming, program data as well as its install folder. Not counting the app data ones in each profile. Opera s pretty good at hiding the folders you need to change anything too. I haven't looked hard for the bookmark folder but I did look for the base file that you need to change or add programs to opera and after a very long time I just quit. I searched all the folders stated . By the fourth time though besides falling asleep my eyes were burning because I started so late so Its possible I just kept over looking it or it was namedd way different than the examples I seen. The only simple way to show directories is to copy / paste or type the default path its probably on. Opera folder is not a direction. More a group policy of all folders of opera. On the hard drive and in the computer are not helpful either btw.

IMy O.S is vista and I was using a high contrast theme and I had the exact problem. It wasn't really grey but blank. I switched to windows classic default theme and changed the fonts in opera settings to any one starting with MS which are microsoft. I changed fonts before I changed themes so that might not have had anything to do with it but I had to include every step I took to fix it in case it was part of the problem.
