I am using magento ce 1.9.1 and the latest version of aoe scheduler (v0.4.3) from https://github.com/AOEpeople/Aoe_Scheduler/tags, because the version from here: http://www.magentocommerce.com/magento-connect/aoe-scheduler.html isn't the latest.
But for a few days the timeline view seems to be crashed and looking weird:

The list view is just working, only the timeline view looking weird. I tried to reinstall again and again and flushed all caches too, but without an effect.
Any suggestions to fix this?
