A dialogue box pops up with the following written in it
The last time you opened FaceOSC_Wekinator, it unexpectedly quit while reopening windows. Do you want to try to reopen its windows again?
If you choose not to reopen windows, you may have to open and position the windows yourself.
If I click on reopen it crashes again with a dialogue box saying FaceOSC_Wekinator quit unexpectedly.
