I alluded to this in my other thread about indexing
When using the restart functionality from dialogs (e.g. on changing plugins) something seems to be happening to the classpath.
Each time I restart I end up with the IDEA 4.5 Look And Feel and the Alloy Look And Feels are not available.
I even explicitly put the alloy jar in idea.bat but it doesn't seem to have any effect.
If I shutdown IDEA then start it up from my Desktop shortcut the Alloy LAFs become available again.
