3 of us share access to 4 company files. Regularly I try to open one of the shared companies, it does the download, opening data base, synchronizing and updating. Then I get the message "This shared company is already open". Even if someone else is in the data in single user mode, I should be able to open the data as read only. Have tried deleting the company files from my computer beforehand but this still happens. it is a nuisance. Anyone know why this happens??
