Workflow could not be saved

Hi,

following issue:

we are 2 persons working on a virtual machine (each user has its own knime aplication) and we are working in the same working directory on a network drive (=Local Workspace)

Now we have noticed that we cant edit the workflow from the other person.

System gives the Feedback:

Workflow could not be saved …

File access problems: \xxx\xxx\xx\workflow-metadata.xml

We can copy the workflow and save it in the same directory without any issue, but we cant update each others workflows

Any Ideas whats wrong?

kind regards

Henri
