Remote Front Panel Problem

[Teddy]

Hi

I am using a TAB control in a VI that is published as Remote Frontpanel.
When changing TAB the controls are often grayed out in the browser even when they are not in the running LabVIEW VI !
A Combo box may also contain the apps default values instead of the values from the running VI !
Any hints to solve this ?

I have login/logout in my application, and i need to auto logout when the last Remote Front Panel User disconnects.
How do I detect that there is no listeners/clients ?
The "connection manager.vi" is password protected, so i can't get any hints from there !

Best Regards
Teddy
