I use Thunderbird and Firefox both on WinXP and Lubuntu 11.10. The profile folders are on the NTFS-partition of Windows and I'm sure that I've edited the profile paths correctly. Windows doesn't show any problems but Lubuntu shows the error dialog saying that another instance of Thunderbird/Firefox is already running..."
The funny thing is, that as soon as I've opened the profile folders in my explorer, firefox and thunderbird can be started. I don't have to change any files or something (Have made some experiments with .parentlock)
Do you have an idea how I could solve this problem, as I don't want to open the profile folders after every reboot.
Thanks in advance!
