There's a problem with loading jscript, etc. in Admin Home (./fmcontent/admin/index.php). It appears fine when going to the other admin 'tabs' (pages like ./fmcontent/admin/topic.php, ./fmcontent/admin/content.php, etc.).
To replicate the problem go to the module's admin Home page (./fmcontent/admin/index.php). Then move cursor to the Modules->System->Blocks menu - actually this specific menu item isn't required, it will do it with any of them. You'll notice that the javascript then goes into a loop causing undesirable effects (randomly flashing menu items). It does not do this if you have any other fmcontent admin page loaded, only with index.php
