If you see other icons than Onlime icons above your files ('tick' or 'sync') this may be due to a problem in the Windows Registry. To resolve this issue, do the following:
Right-click on the Windows icon (bottom left), select "Run" and type "regedit" in the text box.
Navigate to this location in the list: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ explorer \ ShellIconOverlayIdentifiers
Delete the "jottaext" keys and other keys that might come from old programs.
Restart your computer
