* Create a math macro with one parameter, and use it in a formula. * Change the macro definition (not the formula using it.)
Output will be fine. But notice that the on-screen preview isn't updated. The old macro stays on screen.
Worse: Changing the parameter in the macro invocation. From "x" to "y" say. Now, the screen gets updated with the new macro definition, as well as the new parameter. Change the parameter back to "x" again, and notice that the image of the old macro definition comes back. Looks like there is some caching, and the cache isn't invalidated when macros get changed.
I could not get into the lyx website, so no bugzilla this time. Helge Hafting
