I have not been able to duplicate this bug since updating to 1.7.2. That said, I cannot confirm that it has been fixed.

We are using 1.6.2 and this seems to occur with any wiring-based mods we have. For example, we are lagging on a particular X-axis tangental to a 30-block circle around our IC2 e-net. As long as you are in render distance, being within about 5 blocks of this x-axis will throw the root.tick.level outputs. What's interesting is even after you move out of the high tick zone it can take a minute or two for the tick in the F3 menu graph to return to normal. It may just be an artifact of the graph, or it could be related to the bug.

Either way, I hope this gets fixed in 1.7!

EDIT: The lag effect is only observed when a certain distance to the NORTH AND EAST (-Z and +X).

EDIT 2: Note that this is only on SMP, when played with the exact same settings in SSP the tick lag issue was NOT observed.

Please change this to "solved".

Upgrading to the latest Catalyst drivers more or less completely solved the issue. A single right click is still causing a 2nd item to be placed in any slot, but it is happening MUCH less often and it is likely only happening because of the beta drivers.

Apparently my desktop is on 13.3 beta 2, which has apparently been reported by AMD as having OpenGL issues. I am going to install 13.3 beta 3 and see if it fixes the issue.

I noticed this problem is only happening on my desktop, and not my laptop.
My desktop had an HD 6950 and a Core 2 Quad Q9550, and my laptop has an i7 and HD 5870 mobility.

This seems to be video driver related, for specific hardware setups.

In that case, Tom, the problem is that it happens intermittently when dragging the stack around. Not only that, but it only works when I am dragging via right-click, which means I am only working with a half-stack to start with at best. Additionally, it does not divide all the items between all the slots.
