Re: [ jEdit-devel ] Changing L&F at runtime

I got nearly 30 plugins. It'll take a while until I have the time to do
enable one by one to see which causes the problem...
The plugins:
ActionHooks, BufferTabs, ClassBrowser, Code2HTML, CodeHelper, Completion,
Configurable Fold Handler, Console, CppCheck, CtagsInterface, CtagsSideKick,
DirtyGutter, ErrorList, FastOpen, FoldTools, Highlight, InfoViewer, JDiff
Plugin, LucenePlugin, MarkerSets, MenuEditor, Navigator, ProjectViewer,
QuickNotepad, SideKick, SuperAbbrevs, TaskList, Updater, Whitespace.
