Create a memoir document. Insert a figure float, with picture and caption. Mark everything inside the float, insert a minipage. Observe that the lyx GUI now call the caption "meaningless" instead of the usual "Figure #". It is as if a caption somehow was entered outside a float (where they are meanlingless.)
This is wrong, for latex have no problem with this. There are two common reasons for doing this: 1. want to tweak caption placement a bit 2. want to have several captions in a float, e.g. in order to seemingly have two floating figures side by side. This is a common trick which used to work well. Something screwed up in the detection of whether or not the caption ultimately is inside a float? The GUI now gives the impression that a valid operation isn't. The workaround is simple - ignore it for it works in output. Still, this should definitely be fixed for 1.4.1, and if the fix is easy - for 1.4.0 too. Helge Hafting
