VNC viewer jumping.

[walkeraj]

Hi, I installed ProxmoxVE 1.1 on a box and I really love it, but I'm having a problem with the VNC viewer jumping around.

I followed the instructions here

http://www.64bitjungle.com/ubuntu/i...pdate-x-on-hardy-as-the-default-java-runtime/

To get the java plugin updated on my machine.

It works, and I can click "Open VNC Console" to see the console on the box, and that works. The problem is that it keeps jumping diagonally down and to the left. Immediately after opening, it jumps about 25px down and 5px right about every second or so. This makes it kind of difficult to use

It's a javascript bug. The problem seems to be a bug with the way window.resizeBy() is being done in Firefox. It's causing a jump every time wresize() is called, even if it's window.resizeBy(0,0). The following fix works for me:

---------
It still jumps a bit when you resize it, but only if you change the size to be other than the preferred size. Also, it avoids unnecessarily calling window.resizeBy()

Thanks, will include that fix in the next release.

Yeah, I had the same problem until I turned off desktop effects. It would be nice to turn them back on (just for fun), so I'll try this fix out. Thanks!!

I see the above code snipets, but how do you apply them?
