After I noticed some problems a week ago, I re-installed everything (through Synaptic) but that did not change anything. Please let me step-by-step explain what I notice: 1) Start of OMEdit I get the following messages: {{{ [1] 20:18:35 Scripting Notification Skipped loading package Complex (3.2.3,default) using MODELICAPATH /usr/bin/../lib/omlibrary:/home/christian/.openmodelica/libraries/ (uses-annotation may be wrong).
