Hi, I encountered the problem that my floats were not placed according to the !tbp settings in the document layout dialog. When I exported my document to tex I saw that most figures had htbp placement settings. When I remember well, these are the figures I inserted before switching to 1.2.x. So probably something went wrong when LyX 1.2 inported the document that was in 1.6.x format at that time. I fixed this by deleting by hand all placement lines in insets in my LyX file. I guess the problem is caused by the fact that lyx 1.6 specified the location of every individual float to be equal to the global setting. LyX 1.2 uses the global location only for floats that do not have a individual location specified, so it does not overule old settings from 1.6. If I am correct than I think this behaviour should be changed. It would be better if LyX 1.2 would make the global placement variable equal to the values used in the 1.6 document and *remove* all placement specifications for the individual float.
Bye and thanks for the great work! Martijn
