That actually raises another question. According to the VM FAQ the VM always
posts a banner message which can't be removed or altered. So, what happens
if there is no display - does the VM start ok without the banner, or does
it go away in a sulk?

Andy,
I doubt that your problems are due to the license manager connection itself,
unless you do not have enough licenses and actually have to wait for a
license. The problem that I encountered using ION is that the web servers
are often old and usually by far not as fast as new desktop machines. Thus
it takes longer to generate plots, especially if intense calculations are
involved. After creation, these plots need to be transmitted over the
internet, which can take quite a bit of time, if the images are hi-res and
use plenty of colors (and you are on a dial-up). This also causes a slow
down. I do not see, how the VM can help you.
Greetings,
Haje

Thanks for the example! Haje

This morning I found a workaround. Not very nice, but it works:
In the license/lmgrd.opt file I excluded the users, which run the Virtual Machine:
GROUP PROCESSES abcd efgh
EXCLUDE idl GROUP PROCESSES
Nevertheless the behaviour (feature) of the license manager is quite nasty:
As long as it can get a license from the pool, it takes it. If not, it looks for
other possibilities. On my notebook IDL runs under a 'personal use' license, but if the
notebook is connected to our network, it occupies a license from the pool.
Any other ideas?
