Problem With Thai Visa Toolbar

[thaimite]

My Windows implementation of the Thaivisa toolbar RSS display, does not remember which posts I have read for various forums.

I can mark all posts read and delete all posts from the toolbar and momnets later it comes back with 10 or 20 (nver an odd number) of unread items.

I am sure it is a problem with my Firefox, and one one occasion I uninstalled and reinstalled the toolbar which fixed the issue for a few days, but now it has reverted back to its old ways.

When using Ubunu I do not have the problem.

I know I should spend more time in Lunux, but I have various programs I have not transferred yet.

Anybody any ideas for a solution?
