I have VNC v3.5 install. Currently using it to monitor 15 computers. Theses 15 computers are not on local LAN and are all located on remote WAN connections with limited bandwidth. I want to monitor these 15 computers using thumbnail view. I set the settings to get a updated view every 900 sec (every 15 minutes). for some odd reason, the software is still taking up about a consent 200K bandwidth on my WAN. The bandwidth increase as I add more computers to the thumbnail view (or decrease as I remove each computer from the thumbnail view). The refresh time setting does not seem to affect the bandwidth at all. Looks like the software is constantly connected to the remote compouter instead of checking every 15 mins. Did I do something wrong? Any solutions or setting I should apply to decrease the bandwidth usage?

The VNC Manager suppose to put thumbnails in sleeping mode when the thumbnails page is not visible. It also suppose to put them in sleeping mode if the timeintervaled option is selected and wake them up to fetch an update. We will double check that the thumbnails are put into sleep when they are supposed to. If there is a bug it will be fixed in the upcoming v3.6 release.By the way, the 3.6 beta today includes some thumbnail view-cpu usage related optimizations, which will benefit for users using 10 and more thumbnails at the same time.

Upgraded the software to 3.6 beta, but still does not work and having the same bandwidth issue. My 15 thumbnail pulls roughly about 1.5MB (= my entire WAN T1 line...). I even try on differnet computers on a fresh OS installed comptuer
I did notice one thing. The thumbnail does physically refresh every 15 minutes (900 sec), but somehow it keep the connection between the VNC server. I notices this when I did a DOS netstat, the connection seem to be always “established” to everyone of my VNC computers, within this 15 minutes refresh.
Just want to reconfirm, the setting to delay thumbnail refresh time is as follow
Options
Thumbnail Display
Thumbnail Updates
Update thumbnail every “900” seconds
This is the only settings I need to set right? To get it to refresh every 15 minteus (15 min = 900secs) ?
The check box for "Enable automatic status check every X minutes" and "Check VNC server status" is also uncheck. Anything I might have done wrong? Or this just a bug?

The thumbnails keep the connection alive even in when using time-interval mode. But when they are not active they are supposed to active so called "dormant" mode on the server side. When this mode is On, the server is not supposed to send any updates to a client. We haven't looked at this bug yet, but it's in our bugs DB and we will be looking at it soon. To reduce the amount of traffic you might want to turn "Use default connection settings" checkbox on. and in the connection settings enable JPEG or ZLIB compression, which should reduce the amount of traffic used.

We spent some time investigating this issue and found the following. The VNC Manager correctly puts thumbnails in a "dormant" mode when the VNC Thumbnails tab is not active or when the main window gets minimized.
But we found one small bug. While the VNC Thumbnails tab is active, thumbnails are set in the active state no matter in what updates mode you have selected. This bug will be fixed with v3.6 release.
