Bookmap does not open

[ericgrabo_grabo]

No question, just for everyone who stumbles over the issue that on open bookmap just flashes up and closes again, after installing bookmap on a different pc. Nothing worked for me. Now I recognized that the computers have the same Microsoft OneDrive Account, which is synchronizing. That thing is the problem. Deactivate it and it works on both again. I thought I would lose my sanity ^^.
