I've just purchased an 8-port Aten (Altusen) KH1508i KVM over-the-net switch. It comes with both a windows app and a java app through which you can control the screen,keyboard and mouse of an attached PC. There is a serious problem with mouse synchronisation. Using either client, you get both crosshairs (accurately following your own mouse movements) and the normal mouse cursor (of the PC you're accessing) which follows behind and is always several inches out of synch with these crosshairs, rendering some parts of the PC's screen unreachable. I've only seen this behaviour before with really bad VNC apps. It can be solved by ensuring that the PC I'm controlling only has the basic Microsoft mouse driver. But this isn't practical in a repair shop where random PCs are being attached all the time, some of which don't even have a usable windows installation.
I'm not necessarily looking for a solution to the above (allthough that would be great) but what I'm wondering is:-
Is this a problem which is common to all KVM-over-IP switches when administering remotely?
If not, can anyone recommend an 8-port alternative which they've exerience of and which doesn't have this problem?
